The thriller I Came By, written and directed by award-winning filmmaker Babak Anvari, tells the story of a graffiti artist who targets a wealthy man and, in turn, becomes a target himself. The film’s stacked cast includes 1917 star George MacKay, Downton Abbey’s Hugh Bonneville and Emmy winner Kelly Macdonald. I Came By is available to stream Aug. 31.

George MacKay

Toby is a rebellious graffiti artist who tags the homes of affluent, privileged people around London to make a statement about Britain’s elite. He’s angry with the world and with his best friend, Jay, who quits tagging after his girlfriend becomes pregnant. When Toby’s first solo attempt goes sideways, a game of cat and mouse with one of his intended targets turns deadly.

MacKay is a Cannes Film Festival award winner and a SAG and BAFTA award nominee. He starred alongside Jeremy Irons in the January 2022 Netflix film Munich: The Edge of War and is best known for his role as a World War I soldier in the Academy Award–winning film 1917.

Percelle Ascott

When Jay finds out his girlfriend is pregnant, he decides it’s too risky to continue tagging houses with Toby. Incensed by his friend’s unwelcome reaction to quitting, Jay is reluctant to help even after Toby’s grim discovery at Sir Hector Blake’s house.

Ascott is a British-Zimbabwean actor and producer. He plays Harry in the Netflix drama series The Innocents.

Toby’s caring and patient mother, Lizzie, works as a therapist for young people but can’t seem to get through to her son. She’s grown tired of Toby’s disrespect and is frustrated by his inability to hold a job or help at home.

Kelly Macdonald is an Emmy-winning Scottish actor known for her roles in No Country for Old Men, Harry Potter and the Deathly Hallows: Part 2, Boardwalk Empire, Trainspotting, Brave, Gosford Park and Nanny McPhee.

Hugh Bonneville

A charming, well-regarded judge who recently retired, Sir Hector Blake lives in an affluent London neighborhood and is the next target of Toby’s antiestablishment vandalism. But beneath his well-to-do facade, he’s harboring a dark secret Toby stumbles upon after breaking into Blake’s home.

Bonneville is a three-time SAG award winner best known for playing Robert Crawley in the series Downton Abbey and for his role as Henry Brown in the Paddington movies. He’s been nominated for two Emmys, five BAFTA awards and a Golden Globe.
