New Trailer For James Mcfvoy's CALIFORNIA SCHEMIN' Sees Two Scottish Rappers Con Their Way Into the Music Industry

Magenta Light Studios has released the final US trailer for California Schemin’, the feature directorial debut of James McAvoy, and this true story looks like one hell of a ride.

McAvoy also executive produces and co-stars in the film, which turns the bizarre rise of real-life Scottish rap duo Silibil N’ Brains into a funny, chaotic underdog story about friendship, ambition, identity, and just how far two guys will take a lie when their careers depend on it.

The movie stars Séamus McLean Ross as Gavin Bain and Samuel Bottomley as Billy Boyd, lifelong friends from Dundee determined to make it as hip-hop artists during the early 2000s. Their problem isn’t a lack of ambition or talent. The UK rap industry simply doesn’t know what to do with two white Scottish guys sporting thick regional accents.

After London music industry gatekeepers laugh them out of an audition, Gavin and Billy come up with an absolutely ridiculous solution. If nobody wants Scottish rappers, they’ll stop being Scottish rappers. At least as far as everyone else knows.

The pair reinvent themselves as hard-partying MCs from Southern California, complete with American accents, invented histories, and new personas. Calling themselves Silibil N’ Brains, they head back into the industry and discover that the same people who dismissed them suddenly want what they’re selling.

Their fake identities begin opening doors, and the duo eventually manages to fool some major players in the business, including a successful producer played by McAvoy.

Of course, maintaining an elaborate lie while fame starts creeping closer creates a whole new collection of problems. The bigger Silibil N’ Brains become, the harder it is for Gavin and Billy to keep their actual identities buried, and their friendship begins feeling the strain.

That gives California Schemin’ more to chew on than its outrageous premise might initially suggest. The story digs into image, authenticity, class, cultural identity, and an entertainment industry that rejected these guys as themselves before embracing the characters they created.

For McAvoy, that part of the story was especially important. The Scottish actor has wanted to direct since he was a teenager, and he explained what drew him to making this his first feature:

"I've wanted to direct since I was 16. After 30 years of working with and learning from some of the best in the business, that desire has only grown. All this gave me the opportunity to do two things I cared about as a first-time director:

“Tell a story about people from a background like mine: lower-income, council estate kids, with talent, hopes, dreams - and a desire to transcend their limited horizons.

Entertain.

“California Schemin' is about two people who don’t just break through a glass ceiling, they completely ignore it and find a way around. That might sound like a straightforward success story, but if it were, I wouldn’t be telling it.

“We celebrate those who dare to dream in the face of failure, who kick down closed doors with unapologetic, gallus self-belief.

“For me, the heart of the story is if their friendship and sanity could survive the journey: could they stay healthy and true to themselves while adopting personas the industry deemed acceptable, and forsaking the Scottish culture that made them?"

It’s easy to see why McAvoy connected with the material. The scam is funny and almost impossible to believe, but underneath it are two young Scottish guys trying to escape the limitations placed on them. Their solution just happens to involve pretending they grew up thousands of miles away in California.

Ross and Bottomley lead the film alongside Lucy Halliday and Rebekah Murrell, with McAvoy joining the cast as the producer who gets pulled into the duo’s elaborate deception.

The screenplay comes from Archie Thomson and Elaine Gracie, based on the story of the real Gavin Bain and Billy Boyd. Danny Page, Paul Aniello, Simon Kay, and Michael Mendelsohn produced the film.

California Schemin’ premiered at the 2025 Toronto International Film Festival before opening in UK theaters in April 2026. Now American audiences are finally getting their chance to see the movie. It will hit US theaters on October 9, 2026.
