Lots Of Laughs In New 'Avengers: Age Of Ultron' Behind The Scenes Featurette

Some say a happy set makes a good movie. If that's the case, Avengers: Age of Ultron might be the best movie ever. A new behind the scenes featurette for the film, which opens in the US on May 1, shows the cast and crew having a great time making the movie. There are laughs, there are hijinks, there are even some shenanigans. And if that's not enough, there are few new shots in there too. Check out the latest Avengers Age of Ultron behind the scenes featurette below.

Thanks to Marvel UK for the video, which has the UK release date. (The film begins playing in theaters in some countries on April 22, and will roll out globally in the week or so following.)

Seems like there were lots of laughs on that set, with the actors coming back together after multiple movies and public gatherings. It's like they're a big family. Hopefully, that'll translate to the screen.
