The son of director Tim Burton and actress Helena Bonham Carter will make his second cameo appearance in his father’s next movie - at the tender age of three.

Billy Ray Burton, who can briefly be glimpsed in a pram in Willy Wonka And The Chocolate Factory, will crop up in Burton’s upcoming musical Sweeny Todd alongside other actors including Sacha Baron Cohen.

“He’ll be in Sweeney Todd. Billy will always have a role but we’re never going to let him talk,” says Bonham Carter.
