All is By My Side will focus of Hendrix's life before he became famous, a time when he was just a back-up guitarist named Jimmy James. Later, a fan named Linda Keith takes him to London in 1966 where he transforms into Jimi.
In the one-minute, 19-second clip, Hendrix and Linda (Imogen Poots) have a flirty conversation before he flies out to California. During their talk, Hendrix tells his former lover he's written a song about her.
The John Ridley-directed film will make its U.S. debut at South By Southwest in March.
