The results can sometimes feel genuine, like in Fury (2014), or in other instances barely beneficial, like Suicide Squad (2016). However, for Ayer's upcoming survival thriller, Heart of the Beast, it seems that the director had no choice but to go method for the film's star. A new featurette focusing on the two leads of Heart of the Beast has been released online, showcasing new behind-the-scenes footage for the upcoming survival thriller. Ayer, Pitt, and the rest of the production team worked hard to film around the dog's inherent behavior. However, Ayer's film looks to have a much smaller cast of characters, with the primary focus being on Pitt and his dog.
