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 r… - Donald O'Brien

[O'Brien's heroes are] William Butler Yeats, Michael Collins, André Malraux, Maurice Ravel, Giorgio Di Cirico, Laurence Olivier and Max Schmeling. And of course the great Douglas Baader, the war pilot who had no legs. When he was captured by the Germans, they allowed the British to parachute his steel legs. And he escaped! So, I don't care about The Merry Wives of Windsor, but talk to me about Douglas Baader!

[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."

(Sean Connery) was the most conceited actor I've ever worked with! He is rich, successful and handsome...good Lord, why does he act that way? He doesn't want anybody near him! If there was anything or anybody that might have taken the eyes of the spectator off of him, he just went to the director and complained, as if he didn't already have enough screen time! Murray Abraham was so different, such a nice man...And there was one brilliant German or Austrian actor on this movie who looked like Falstaff, big, fat guy, a marvellous presence. Helmut Qualtinger was his name. He was terrific!
