Lennon biopic headed to the big screen

John Lennon's early life will be the subject of "Nowhere Boy," a film based on a book written by Lennon's half-sister Julia Baird. Matt Greenhalgh, who wrote the award-winning Ian Curtis/Joy Division biopic "Control," is developing the script. Casting is reportedly underway for the movie, which is set to be filmed on location in Liverpool. Here's what Greenhalgh has to say about tackling the story of one of rock's great icons.

"When looking for my next project I was wary of musical protagonists - but when John Lennon was floated, that vanished. He is beyond music; above it even," Greenhalgh told Britain's Guardian newspaper. "And his early life as told in Julia's book took me into a world that illuminated so much about this legendary genius. I could see the drama and film immediately. The women in his life, the men who weren't, the birth of rock'n'roll; all imposing on a brilliantly complicated adolescent mind. The nagging questions, the icy secrets, the need for love. John's angst and anger pouring out into his music, his thankful salvation. Without this story we would never have heard the Beatles - can you imagine that?"
