Michael Caine was so very much beside himself to be working with Laurence Olivier on the set of “Sleuth” (1972) that he didn’t even know how to address him. Eventually, he broke down and just asked. Olivier replied, “Well, I am the Lord Olivier and you are Mr. Michael Caine. Of course, that’s only for the first time you address me. After that I am Larry, and you are Mike.”
