Cokeliss added: "I'm really excited to be joining Home Corp. It's a young company with great energy and a really stimulating bunch of intelligent, young people."
Cokeliss began his career with two short films - Tea and Queen's Park Story - which were named Best of the Fest at the Edinburgh Film Festival in 1998 and 1999. He is currently working on a Lexus film for Dentsu Canada and an Adult Literacy campaign for The Bridge in Glasgow.
