Legendary actor and dancer Donald O'Connor's own story is pure Hollywood. Literally singled out by a talent scout during a stage performance, O'Connor instantly went from traveling Vaudeville performer to a star on the screen during one of the most spectacular eras moviemaking has ever seen. With a resume over 70 films long, the 77 year-old O'Connor can rest assured his place in cinema history is golden. Now, as his most memorable film Singin' in the Rain is set for a 50th anniversary DVD release, the man trained by acrobats looks back on making the world's most famous movie musical. Interview by Karen Idelson

Singin' in the Rain may be the world's most famous and most loved movie musical. What's it like to look back at work you did 50 years ago and realize it had such an incredible impact?

I think it's absolutely wonderful. I think really with this kind of energy behind it, it's like the very beginning of the movie when you've just previewed, and you go out and talk to various press around the country. It's very exciting. It's wonderful.

You were all on a tight schedule shooting this film and a lot of the "effects" in this film had to be done right there on the set. Do you remember how it was to work under those conditions?

I think the funniest to me is when Gene was filming the main title song Singin' in the Rain out in the rain. They were on the back lot and, of course, it was open and they had to enclose it with a tarpaulin. When they started, he's signing, so happy and he looks great, and the rain is coming down, and just at a perfect timing each droplet seems to have its own beat.

All of a sudden somebody takes a close look at Gene and he's shrinking. The clothes are actually shrinking. No one took into account that the tweed material shrinks, so they're going crazy trying to find cloth now to make him suits. About every 30 minutes, they'd have to make another suit for him. Actually you'd be talking to him in between shots, and you'd actually see the material start to rise in his pants and his cuffs. It was really hysterical; it was funny. Gene was a dignified man, and particularly in his work. When all of this started to happen beyond his control, it got to him too. He was hysterical. That to me is about the funniest I've ever seen in anything.

Your signature number in this film is "Make ‘em Laugh." How that number developed and how long did it take to film?

The number started, but naturally Roger Eden came to me and handed me this music, Make ‘Em Laugh. I looked at, Gene looked at it, and he said, "Why don't you take the girls," Jeanie Coin, and Carole Haney, his assistant choreographers, "and see what you can come up with?" So I said okay. I got a pianist, I took the girls into a rehearsal hall, and I began to sing and did a pratfall. They laughed and I said write that down.

Whatever they laughed at the most, that's what we did on the screen. Most of that stuff that you see is done for the first time and it stayed there.

How long did it take to film it?

One day. Yes, I had to do it in one day because my body, as I progressed in the number doing pratfalls, it was on cement. They couldn't give me good old wood. Anyway, I'm doing these pratfalls on cement, and my body, my knees, ankles, and toes, everything started to hurt. We saw right then we had to shoot fast, get the number done in one day, and we did it. We did it in one day and it was absolutely miraculous.

Now two days later I go in on the set, and I get applause from the guys with the lights way up high and the people on the floor, like the opening of a Broadway show. I said isn't this marvelous? Stanley said, "That number is just great. It's fantastic. Do you think you could do it again?" I said oh, sure, anytime. He said, "Well great, you're going to do it again tomorrow."

What had happened was they had inadvertently, the cinematographer or one of his assistants didn't see that the aperture on the camera wasn't correct. It was open and it stuck, so that whole number was fogged out. It looked like a ghost doing his thing. So I had to do it all over again.
