Innes was born in Stepney, East London, and began his career on the stage with the National Theatre of Great Britain under Laurence Olivier.
Before that, he trained at Toynbee Hall and evening classes at the London Academy of Music and Dramatic Art (LAMDA),[1][2] where he was awarded the Shakespeare Cup for excellence.
He appeared in the Bernard Kops play The Dream of Peter Mann at the Edinburgh Festival and on a tour of Great Britain, directed by Frank Dunlop, under whom he had trained at Toynbee Hall and LAMDA.
In March 2010, he performed Tribute at the Barron's Court Pub Theatre in London, receiving these reviews: "... the whole show centres around a superb talent: not Gielgud's but that of George Innes.
