Simon Helberg played the piano in Florence Foster Jenkins.

Jake Gyllenhal learned the guitar to play Johnny Cash in Walk the Line.

[Southport Zeb]

Jake Gyllenhal learned the guitar to play Johnny Cash in Walk the Line.

He must have been disappointed when Joaquin Phoenix got the part

[Antepli Ejderha]

Joaquin Phoenix I think, who also learned to sing.

Harvey Keitel, bad lieutenant

[Felicity, I guess so]

I believe (...) Gene Hackman was really playing sax in The Conversation

[Uros Predic]

Ewan McGregor may've played the tenor horn in Brassed Off. He can, or at least could, play the French Horn so it wouldn't have been a stretch instrument-wise.

Although given all the music involved in the film, plus a lot of random Yorkshire voices, has been dubbed on its likely he didn't need to.

[Benjm]

Likewise, learning the saxophone for New York, York was one of Robert De Niro's renowned feats of immersive preparation in his early career but it was just to make his playing scenes look realistic. He doesn't feature on the musical soundtrack.

Shit,embarrassing. I had a feeling I was wrong, but I was posting during a break in play In the Dundalk v Bohs game , and didn't have time double check .

Michael J. Fox didn't sing or play guitar in Back to the Future, despite most people thinking he did.

[Gangster Octopus]

Far more importantly, did you manage to get to the match?

[elguapo4]

No, watched it on my laptop, we won 1.0

[Gangster Octopus]

Semi-shame.

[tee rex]

George Formby. Elvis Presley.

Although we can't be sure they all played their own instruments. I'd be surprised if Simon Helberg did.

[delicatemoth]

Charles Aznavour in Tirez Sur Le Pianiste.

[gjw100]

Miles Teller in 'Whiplash'

[Levin]

Now there's a film that had no impact past awards season.

[Snake Plissken]

David Graf (Tackleberry) played saxophone in Police Academy because a) he could and b) that curious Hollywood bye-law that required a sax solo in every film made from 1983-1988.

[Stumpy Pepys]

Deliverance

[MsD]

Keira Knightley, in that film where she plays guitar and sings.

[MsD]

And Johnny Flynn, in Stardust .. and *I think* on the theme of Emma (he sings the theme and sings in the film).

[MsD]

Bradley Cooper learnt guitar and piano for A Star is Born; of course Lady Gaga was already expert at both.

[Nefertiti2]

Benny Goodman in his role as Professor Magenbruch in A Song is Born the musically astonishing but otherwise inferior remake of Ball of Fire also featuringTommy Dorsey Louis Armstrong Lionel Hampton aand the Golden Gate quartet as themselves.

[ChrisJ]

I liked that film.

Tom Hiddleston - I Saw the Light.

[Stumpy Pepys]

I believe Hugh Grant learned guitar for the final scene in About a Boy.

[Stumpy Pepys]

Michael Douglas said he didn't learn piano to play Liberace, but said he learned the right places to put his fingers. Does that count?
