There are a couple of things the Marvel Cinematic Universe is known for; comedy, innovation, a ton of CGI. However, there is another thing these series of films are known for; gratuitous shots. Whether it's a shirtless Chris Hemsworth or a butt shot of Scarlett Johansson, the films do like to pander to fans once in a while, though that isn't always a bad thing.
Interestingly enough, Marvel seems to be looking for a body double to partake in one of these "money shots" as an advertisement for a film called Mary Lou - which is the working title of Avengers 4 - is looking for a butt double. The requirements needed for the role seem to match Scarlett Johansson, who will be playing Black Widow in the film and is set to have a bigger role.
Having a butt double might seem odd but when you consider how busy these actors and actresses must be, it's a bit understandable. Plus, it does save these actors from doing these fan-service scenes so that they can focus on the more important details of the film. Still, this will be a popular conversation topic with fans since sex does sell, even with a Marvel film.
Avengers 4 is coming to theaters on May 3, 2019. The film is set after Avengers: Infinity War, though plot details are slim to none.
