In his biography. Michael often mentions Roger as the kind of friend whom you don't have to ask for help, because he'd always offer it first himself.
Here's a small exerpt from the book that describes (in Michael's words) how the two met for the very first time:
The most satisfying and beneficial sign that the play [the Compartment] and I were a success came a little while after it was broadcast. Terry and I were walking along Piccadilly when we saw Roger Moore on the other side of the road. He was already famous in England for the series Ivanhoe, and just like anybody else we were thrilled to see someone famous in the flesh; we were standing there gawking at him when he spotted us and came across the road. We both wondered who he had seen and were looking around to see if there was anybody else behind us, but no, he was walking towards us and he was smiling straight at me. I smiled back nervously and he stopped right in front of me and said: "Is your name Michael Caine?" I told him that it was. "I saw you in the television play "The Compartment", he went on. "I just want to tell you that you are going to be a big star." He shook my hand and walked away, leaving me stunned and delighted. It was the biggest compliment that I'd had since Dennis Price wrote to me.
After thirthy years of friendship with Roger, I can still count the differences between us on one hand, several of which were apparent that first time we met. He was famous, handsome, elegant and generous; I was obscure, ugly, scruffy and mean. I've caught up with him since on at least two counts. And two out of four's not bad.
