Graham trained at Homerton College, Cambridge studying Physics and Education. He taught Physics, Chemistry and Mathematics for 5 years at Rosebery School, Epsom before re-training as an actor at the Guildford School of Acting. 

In 1988 he co-founded the Kinetic Theatre Company for which he has been writing and producing ever since. He lived in Geneva for 2 years where he worked on Play It Again Sam for the Little Theatre of Geneva and in this country Graham acts under his Equity name Oliver Graham. Theatre credits include Laurence in Abigail's Party; Teen Angel in Grease and he created the role of Gary in a new play, Something For The Grown-Ups. Film credits include playing a drug-smuggling Mafioso mobster in Aardvark Films Nothing To Declare and, most recently, Antonio in the full-length feature of Twelfth Night with Egotrip Productions.  He has just completed working on the Premiere West End musical Peggy Sue Got Married.

About writing for Kinetic he says:

"Having been a teacher I know how hard teachers work, so I always like to write something into the plays, albeit a bit tongue-in-cheek, especially to make them smile too!"
