In 2013, Baron Cohen was set to play Freddie Mercury in an official biopic sanctioned by the surviving members Queen, but things didn't go quite as planned, resulting in him leaving the project.
According to Baron Cohen, creative differences arose from Queen's desire to make a substantial portion of the movie revolve around the band's post-Mercury career—a prospect he found uninspiring—while shying away from the prolific singer's legendary debauchery. "Brian May is an amazing musician," Baron Cohen told Howard Stern, "but he's not a great movie producer."
May didn't like that, not one bit. "Sacha became an arse," May explained while telling his side of the story. "We had some nice times with Sacha kicking around ideas, but he went off and told untruths about what happened. Why would he go away and say that we didn't want to make a gritty film? Are we the kind of people who have ever ducked from the truth? I don't think so … It's obvious that it wasn't going to work, him playing Freddie. It wouldn't suspend your disbelief."
Unfortunately, we'll never know if Baron Cohen would've made a good Freddie Mercury, and the project has only continued its long tradition as a problematic production.
