This includes those portraying straight roles, reversing the common practice of casting straight actors as queer characters, making a powerful statement, and holding a mirror to how the LGBTQ+ community has been portrayed in media over the years. Once the decision was made to have the character Aaron played by an openly-gay actor, Eichner and Stoller decided to have the entire cast be openly LGBTQ+ actors. The writers originally planned to have a famous straight actor play the love interest opposite Eichner, but it was decided that this did not make sense for the story, and worked against what the film was trying to communicate. Bros will be the first gay romantic comedy to come from a major studio that features an entirely LGBTQ+ principal cast. This is not just any gay rom-com film, though. Eichner was approached by Stoller in 2017 and asked to collaborate on the film, which needed an openly gay co-writer, much like the character he portrays in the movie. Stoller, who is known for his work directing the 2008 comedy Forgetting Sarah Marshall, helms the upcoming film and has co-written the movie with Billy Eichner. Bros is a first of its kind in many ways.
