Johnny Depp has been named as the frontrunner by bookies, but he's just one of several names that are now in the mix, so we've narrowed down our top six choices for the role of Mercury.
Despite looking nothing like the Queen frontman, Depp is a hot tip for the role on star power alone. He's got singing experience from Sweeney Todd. He's shared a screen with Keith Richards, so acting alongside someone pretending to be Brian May will be a doddle. He's also got bona fide rock cred having recorded with Oasis, Shane MacGowan and Marilyn Manson.
Having played Keith Richards, a version of Bob Dylan and Sebastian Flyte, we're confident that Ben can pull of the necessary mix of rock 'n' roller and foppish eccentric. And, believe it or not, Mr Whishaw can actually hold a note, singing for the part of Ariel in Julie Taymor's 2010 film adaptation of The Tempest. And like Freddie, you can lose yourself in his face for days and days...
He might seem too spindly to be Freddie, but we think he could pull off his early long-haired rocker years quite well. Brand played a musician in Forgetting Sarah Marshall, and would be able to channel his own chequered past into depicting the singer's excesses. Post-Sachsgate, he also understands some of the media intrusion that Mercury had to deal with.
Despite performing with Brian May and Roger Taylor, at 63 years old we don't see Free's Paul Rodgers as a serious contender, but having "replaced" the late Freddie for the 'Queen + Adam Lambert' live shows, the American Idol runner-up must be considered. A star on both sides of the Atlantic, May has repeatedly called him an "amazing artist" and "a very nice guy".
Anne Hathaway may have got most of the plaudits, but the real revelation in Les Misérables was Hugh Jackman's incredible vocals. Of all the names on this shortlist, Hugh is the one who can best combine top-notch acting with a singing voice approaching the quality of The Great Pretender.
From Spider-Man to Tristan & Isolde, Pineapple Express to Eat Pray Love, few actors have the range of Franco. His turns as Allen Ginsberg in Howl, Scott Smith in Milk and Aron Ralston in 127 Hours show that he can inhabit a real-life character. Plus... he's James Franco!
