James McAvoy, after giving some outstanding performances as an actor throughout the years, has tried his hand at film direction. His directorial debut, California Schemin’, recently got a trailer on YouTube. StudioCanal dropped it and boasts over 73k views, which keeps growing as we speak.

The news about the actor's directorial debut came out last year in May, when he told Deadline that,

"I’m proud to announce that for my directorial debut I will be telling the true Scottish story of Silibil ‘n’ Brains. California Schemin’ is as rooted in the California rap scene of the early 2000’s as it is in the working-class Scottish setting where our story begins. With California Schemin’ I’ll be telling a story about friendship, rap and glorious failure that has the potential to move, shock and entertain."

Silibil ‘n’ Brains is a rapper duo from Scotland consisting of Gavin Bain and Billy Boyd, two Scottish lads who disguised themselves as individuals from California so that people in the music industry would take them seriously.

A documentary has also been made on their story, dubbed The Great Hip Hop Hoax, directed by Jeanie Finlay, and garnered positive reviews from critics.
