I'm not a big fan of biopics of musicians because they rarely get it right. There are three musician biopics that stand out from the rest of the mediocre ones.
Control, the Ian Curtis biopic was the rare exception because Sam Riley is such a talented actor and singer. I was shocked to find out that it was Riley, not Curtis singing on the soundtrack.
I was also impressed with Val Kilmer's portrait of Jim Morrison in Oliver Stone's
The Doors. Kilmer sang reasonably well in a couple of the live concert segments. Kilmer got the part by sending Oliver Stone a homemade video of himself signing a few Doors songs.
The final good music biopic is
Bird, Clint Eastwood's 1988 portrait of jazz saxaphonist Charlie Parker. Forest Whitaker played Parker and he should have won an Oscar for it, but the movie got snubbed at by the Academy, after both the Golden Globes and the Cannes Festival both gave best director to Eastwood and best actor to Whitaker.
Most of the actors mentioned to play Hendrix in a biopic are way too old to play Jimi, who was 27 at the time of his death. Eddie Murphy is 49, Will Smith is 42 and Prince is 51. I don't think any of those three have the acting talent to pull off a believeable Hendrix especially Prince who is about as good an actor as Elvis was.
Casting the Hendrix role is challenging because it takes both a good actor and a good guitar player to pull it off in any sort of convincing manner. Forest Whitaker spent a couple of years learning how to snych the saxphone keys to Charlie Partker's playing and it nearly impossible to fake electric guitar playing, especially when you're trying to fake Hendrix.
The only person I can think of is blues guitarist Chris Thomas King who played a blues guitarist role based on Tommy Johnson in
Oh Brother Where Art Thou. But King is well into his forties and has very different facial features and body type than Hendrix.
The guy who played Hendix in cable television biopic did an okay job but if I remember correctly he didn't have any scenes where he had to play guitar or sing which made his task much easier. There has been a biopic of Frank Sinatra's early years but I can't remember the title or the actor who played Sinatra.
