Gibson is to direct DiCaprio in an untitled period drama set during Viking times, according to the film industry bible, which reported that veteran script writer William Monahan also has signed on to the project.

"This will be an awe-inspiring story, created with some of the industry?s finest cinematic talent and I am just over the moon to be making this film with Mel, Leo and Bill," said the film's producer Graham King in a statement.
