I met the walrus (2007)

The film is based on an interview of John Lennon by Jerry Levitan in 1969. Levitan, then 14 years old, tracked Lennon to his hotel room at Toronto's King Edward Hotel after hearing a rumour that Lennon had been sighted at the Toronto Airport. Jerry made his way into John Lennon's suite and persuaded John to agree to an interview. The animation is based on Levitan's historic 30 minute recording of the interview, which was edited down to 5 minutes.
