For more than 30 years, Akio Sakurai has been obsessed with studying and recreating the minute details of every recorded performance of Led Zeppelin guitarist Jimmy Page.

Name the date and the place of the concert and Sakurai can play the song as Page did — the same timing, phrasing and tone, not to mention wearing the appropriate duds, including a perfect facsimile of the black dragon suit, right down to the colors of the stitching.

"Mr. Jimmy," a new documentary film by American director Peter Michael Dowd, follows the 55-year-old Sakurai on his journey from playing basement clubs in Tokyo to joining one of the longest-running Led Zeppelin tribute bands in Los Angeles to playing with Jason Bonham, the son of the late Led Zeppelin drummer John Bonham.
