#40: I’m Singing in the Rain
We’re going to sound cliche here, so we apologize in advance, but maybe Gene Kelly shouldn’t have been singing in the rain! Okay, sorry for the bad joke. We’ll see ourselves out. Seriously, though, this kind of commitment and dedication is what great actors are made of – agree or disagree?

While filming his iconic number for “Singin’ in the Rain,” he was apparently suffering from a bad cold and fever. He was afraid he would catch pneumonia, but that didn’t happen, as far as we can tell. We don’t know whether or not he regretted the decision to work while he was sick, but Singing in the Rain went on to become one of the most popular musicals of all time.
