Have to disagree with the recommendation of All Is By My Side:
The music is wrong
The 'facts' are wrong
The portrayal of Jimi's personality is wrong
Not a good start for a biopic. And the guy who made the film said, when asked about the inaccuracies, that it wasn't his job to correct false info floating around - it's the responsibility of the people being lied about. Some attitude for someone trying to make some money off someone's name and life story! Here's a review from Jimi's girlfriend Kathy Etchingham (more to be found by googling her and The Guardian).
Try, as suggested elsewhere, A Film About Jimi Hendrix, Jimi Hendrix - Voodoo Child - or PBS's Hear My Train A Comin.
