Pacino's fictional rocker rediscovers his muse after reading a letter from his Beatles hero

Al Pacino is to star in a new movie about a fictional rock star who turns his career around after finding a letter from John Lennon.

Titled Imagine after the iconic Lennon song, the film is the pet project of screenwriter Dan Fogelman, who will direct from his own script. Fogelman’s screenwriting CV includes Crazy, Stupid, Love. and Cars, but this will be his first time as director.

Deadline describes Pacino’s character as an “ageing 1970s rock star” with a decadent lifestyle and a much younger wife. He can still sell out arenas playing the same old hits, but has lost his creative fire.

On his 64th birthday, he discovers an undelivered letter written to his 19-year-old self by John Lennon. After reading it, he resolves to sort out his lifestyle and return to the music he originally set out to make.

Jeremy Renner will co-star as his long-lost son, while Julianne Moore will play the owner of the hotel he checks into in a bid to reconnect with his songwriting muse. Imagine is expected to begin filming in April or May next year (2013).
