In the first clip of Gene Kelly (after he has become a star) in the silent "Action" movie in "Singing in the Rain", right after the title saying "I hear a footstep", Gene runs through a door to find a guard rushing down the stairs towards Gene. The guard tries to stab Gene with a spear, and Gene grabs him and throws the guard over the lower stair rail. Then as the guard pitches over the rail, in the very lower right hand corner of the screen you will see a left hand (wearing a watch) reach up to try to catch the guard's leg!
