“Bros” did not bring big audiences out to the theatre, and its star thinks he knows why.

In its opening weekend, the Judd Apatow produced comedy came in fourth at the box office, earning just $4.8 million.

That number put it well behind the no. 1 movie, “Smile”, which earned approximately $22 million, and behind holdovers “Don’t Worry Darling” and “The Woman King”, which each brought in about $7 million.

After news of the less-than-stellar returns for “Bros”, co-writer and star Billy Eichner took to Twitter to share his reaction to his LGBTQ-themed rom-com flopping.

Describing seeing the movie at a sold out theatre in L.A., Eichner said the audience “howled with laughter start to finish,” adding, “I am VERY proud of this movie.”

But he also shared, “What’s also true is that at one point a theatre chain called Universal and said they were pulling the trailer because of the gay content. (Uni convinced them not to).”

Admitting “that’s just the world we live in, unfortunately,” Eichner pointed to the film’s good reviews and great CinemaScore rating with audiences, and added, “straight people, especially in certain parts of the country, just didn’t show up.”

Eichner also urged, “Everyone who ISN’T a homophobic weirdo should go see ‘BROS’ tonight!” promising, “You will have a blast!”

Despite the low box office returns, the studio will likely be hoping that strong word-of-mouth gives the film some staying power in theatres as they try to earn back its $22 million production budget.

Starring an entirely LGBTQ main cast, the film also features Luke Macfarlane, Bowen Yang, and more.
