Writing a sequel to the classic children's novel, Chitty Chitty Bang Bang

Almost 50 years since it was created, Chitty Chitty Bang Bang is being brought back to life.

Frank Cottrell Boyce explains on BBC Radio 5 live why he is writing a sequel: "People will have expectations from the film, but they're not really in the book."

"It's been the most fun I've ever had writing," Cottrell Boyce tells Rachel Burden and Phil Williams. "It's just been like being a kid again, playing with it!"
