“Some people move on. But not us.”
Just as Super Bowl LIII got underway, Marvel dropped a second teaser trailer for Avengers: End Game, the hotly anticipated follow-up to 2018's Infinity War. There's some new footage, but very few hints about what we can expect when the movie premiers this spring.
(Spoilers for Infinity War and Ant-Man and The Wasp below.)
In Avengers: Infinity War, Thanos (an intergalactic supervillain from Titan) successfully collected all six Infinity Stones: the Power Stone, the Space Stone, the Time Stone, the Reality Stone, the Soul Stone, and the Mind Stone. Once collected and placed in the Infinity Gauntlet, they gave Thanos the power to wipe out half of all living beings in the universe. And despite the valiant collective efforts of pretty much every superhero in the Marvel cinematic universe, Thanos succeeds. With a single snap of his fingers, half of the universe dissolves into dust, including many of our beloved superheroes.

New research suggests that post-release movie piracy through The Pirate Bay is linked to increased box revenue. The counter-intuitive finding is driven by word-of-mouth promotion. The effect, which does not apply to pre-release piracy, results in rather interesting policy implications.

Late 2014 The Pirate Bay went offline after Swedish police raided a datacenter near Stockholm.
The downtime lasted over a month and many users feared that it was the end for the notorious site.
It wasn’t. The Pirate Bay came back and continued on its merry way.
While many people have since forgotten about the incident, marketing professors from business schools at the University of Houston and Western University used the downtime to research its effects on box office revenue.
Hollywood’s general logic is that piracy hurts box office revenues. However, there is also some evidence of positive effects through word-of-mouth promotion. Using the Pirate Bay downtime as a natural experiment, the researchers tried to find out if that’s indeed the case.
“It is natural to focus on the downsides of piracy for movie makers — and these can be significant — but many will be interested to note that piracy can have an upside,” Professor Shijie Lu informs TF.
Through their research, Lu and his co-authors Xin Wang and Neil Bendle, investigated the effect of this “buzz” in detail. They published their findings in a paper titled “Does Piracy Create Online Word-of-Mouth? An Empirical Analysis in Movie Industry.”
Movies shared on The Pirate Bay are the main focus. The researchers use the Pirate Bay downtime following the 2014 raid to measure its impact on word-of-mouth promotion and box office revenues.
Based on a sample of hundreds of movie torrents and data from most popular movie review sites, Lu and his colleagues estimated this effect. Their results are rather intriguing.
First off, the findings clearly show a negative effect of pre-release piracy on box office sales. This result is consistent with previous studies and an increase in “buzz” doesn’t do enough to offset the negative effect ..
“The impact of pre-release piracy is found to be negative regardless of piracy type. The total box office revenue is reduced by 11% due to the existence of piracy appearing before the movie release,” the researchers write.
This changes when the researchers look at post-release piracy. That is, piracy which occurs after a film has premiered at the box office. In this case, there’s a positive effect on box office revenue through an increase in word-of-mouth promotion (WOM).
“We find that the volume of online WOM mediates the impact of piracy on the box office. Based on counterfactual simulations, the WOM-effect from post-release piracy on the box office increases revenue by about 3.0%,” they write.
In other words, when The Pirate Bay went down, box office revenue dropped as well. This effect is significant and not linked to seasonal changes, as it wasn’t there in previous years.
The positive effect is strongest during the beginning of a movie’s release and differs per genre. Action movies, comedies, and thrillers, benefit more from a positive piracy “buzz” than dramas, for example.
While the findings suggest that The Pirate Bay does help to generate buzz and bring in more revenue, the overall effect isn’t positive. The negative pre-release piracy impact is higher than the positive post-release effect, after all.
“Pre-release piracy can have a substantial negative effect, in our data this overwhelms the positive effect we look at. That is, the overall effect of piracy is still negative,” Lu tells us.
That said, there is an interesting lesson to be learned. Based on this study, copyright enforcement should be mainly targeted on early leaks. If these are dealt with, the main problem is ‘gone.’
“Our findings suggest approaches to target scarce anti-piracy resources, such as focusing on tackling damaging pre-release piracy,” the researchers write.
These results offer yet another piece of the piracy puzzle. It’s worth noting that the number of torrents was used as a piracy indicator in this study, which isn’t perfect. Follow-up studies with more granular data and actual download estimates may provide further insight.

Writer/Director Dan Gilroy weaves a tangled web of money, sex, and murderous art.
An obscure artist dies and leaves behind a trove of strangely alluring paintings, becoming a posthumous success, in the Netflix original film Velvet Buzzsaw. It turns out to be literally art to die for.
(Some spoilers below.)
Rene Russo (Frigga in Thor) and Jake Gyllenhaal (Mysterio in the forthcoming Spiderman: Far From Home) co-starred in writer/director Dan Gilroy's 2014 thriller, Nightcrawler, a dark, disturbing tale that skewered the "if it bleeds, it leads" mentality of broadcast news. The triumvirate is back in top eccentric form with Velvet Buzzsaw, this time targeting the indulgent narcissism and greed of the Los Angeles contemporary art scene.
At races like Le Mans, amateurs compete alongside the pros. But why?

Over the years there have been a number of good documentaries on the world of endurance racing. There's just something fascinating about the motivation and perseverance needed to compete at the highest level in long distance classics like the 24 Hours of Le Mans. Back in the 1970s there was Le Mans, the Steve McQueen movie that, while it has a plot, is really closer to a documentary—after all, there's not a word of dialogue for the first half-hour. In the late 2000s we got the wonderful Truth in 24, about Audi's highly successful Le Mans program, then a sequel. More recently we've had Journey to Le Mans and Sir Chris Hoy: 200mph at Le Mans, and now Netflix has just added The Gentleman Driver.
As the name suggests, this latest documentary looks at the role of the amateur racers that compete at the highest level of the sport, in the World Endurance Championship (WEC). Of the four classes that race at Le Mans and in this series, two of them are for pro-am teams. As the documentary explains, OEMs come and go as corporate priorities change, but the wealthy amateur has always been the backbone of the sport, and some of them are actually quite good at it. As we both happened to be at Daytona at the end of January, I got a chance to chat with Paul Dalla Lana, one of the drivers featured in the documentary, to find out a bit more about why he bothers spending so much time and money on this sport.
"Good teammates and a good team always make the difference. The sport has a big tradition of gentleman drivers being involved, it's something that drives the customer side of racing all around the world, and now more and more you're seeing these opportunities to merge in with factory racing and the truly pro configurations. It's a great part of the sport and it's nice that so many of us gentlemen are having success out there and pushing ourselves to places you never thought you'd be, right? Because it's one of the cool thing about this sport—you can really go up and compete at the highest level if you're prepared to put in the time and energy. There's not too many sports that afford you that opportunity."
As it turns out, Dalla Lana's story isn't that of a kid who grew up racing then had to give it up, only to return to the sport once he became financially successful in other endeavors. So when exactly did he start racing?
The figures are visible under UV light; other paintings may also have hidden drawings
Jean-Michel Basquiat, the late neo-expressionist whose tragic life story inspired a 1996 film, used invisible ink to draw secret figures in at least one of his early paintings, Artnet News reported last month. The figures are easily visible under UV light, and more of the artist's work from this period may contain such hidden drawings.
Invisible ink has been around since at least the fourth century BC; it's mentioned in a treatise on secret communications by Aeneas Tacticus. It's familiar to anyone who has ever gotten their hand stamped when they entered a club so they could be readmitted later by holding it under UV light. There are many different types, but substances that glow in response to UV light include lemon juice, body fluids (hence the use of UV light in forensics), sunscreen, and some soaps and laundry detergents.
But invisible ink is rarely used by artists. One notable exception is the Chinese-born British artist Aowen Jin, whose 2015 exhibit at London's Horniman Museum featured a series of hand-drawn invisible-ink illustrations, which can only be seen under UV light, on the walls and floor of the Music Gallery Performance Space. Apparently, Basquiat sometimes used fluorescent materials, and signed one 1982 canvas, Orange Sports Figure, in invisible ink. But this is the first known instance of the artist intentionally embedding secret drawings into a painting.
