The funnyman, who previously showed off his singing in movie musicals Sweeney Todd: The Demon Barber of Fleet Street and Les Miserables, is due to play the late Queen frontman in a new project.
Filming is due to kick off this spring (13), and Cohen is now reportedly training with a vocal coach to make sure he can hit the high notes just like the late superstar.
A source tells British newspaper The Sun, "Sacha is a huge Queen fan and is focused on getting Freddie's mannerisms, style and speech perfect. He is working on building his vocals. It is a uphill task, because Freddie has such a unique power and tone."
The film is scheduled for a 2014 release.
