Well known for being a "method actor", Harris was once told that he would play the role of a filthy character, and so he went for a long time without bathing to fit in to the character better, much to the chagrin of his co-stars, who claimed that they could smell him coming a long way away.
While living in England, Harris popped out for milk and when seeing the paper he noticed that Young Munster were playing in Thomond Park, Co. Limerick, Harris got the next available flight to Ireland. He spent the following 3 weeks on a drinking binge. All was unknown at the time to his wife, who had no idea where he was. When he finally returned to England, he rang the doorbell of his house. His wife answered the door and before she had a chance to say anything, he said, "Well, why didn't you pay the ransom?".
While still a student, he rented the tiny "off-West End" Irving Theatre in London and directed his own production of Clifford Odets' "Winter Journey (The Country Girl)". The critics approved, but the production used up all his savings and he was forced to sleep in a coal cellar for six weeks.
