In all these years of recuperaion, I over-used one half of my body. So, when I did a short sprint on the beach, I just fell and couldn't get back on … - Donald O'Brien

Because I was stupid, I said, To hell with it, and I joined a drama school. [It was a ridiculously little school, which was first run by a very clever woman, but she soon was replaced by] "a nitwit, who had read a few books on the Actor's Studio and was very much into analysis, instead of teaching us how to walk and talk!"

I always preferred those movies I would have a large role in. If I had to choose between a small movie with a big role and a big movie with a small role, I'd take the one with more screen time. It's not very satisfying for an actor to get work and then ending up on the cutting room floor.

[O'Brien joined the Dublin Gate Theatre) where Orson Welles had started. Very few people know that he started in Dublin, most people think it was the Mercury in New York. James Mason, Peggy Cummins, Edward Mulhare - they all used to work for the Gate Theatre. My father was extremely furious when he found out that I was wasting my time being an actor. He also got wind of the fact that the star of the production (Micheál Mac Liammóir) was one of the biggest queens alive. He also played the part of Jago in Orson Welles' OTHELLO. This really didn't help. He cut my money off."
