In keeping with the "Creep" theme: A little sideline story.
A slow creep is sometime referred to as "A Mickey Rooney".
A number of years ago I did a Xmas movie of the week with Mickey. We had a scene setup following Mickey as he's chased through a mall. About 100+ of rail with a push down following and doubling back with a close up of Mickey as he "ran" past camera. Thanks to setup time and Mickey, it had to be a one take wonder.
We did 10 plus rehearsals with Mickey's stand-in - for stunt player's timing (getting knocked off escalators, etc). Then Mickey came in and watched a rehearsal. At this point I'm winded. Mickey came over and proceeded to tell me to be on my toes as he was going to me twice as fast as his 70 year old stand-in - who was chugging pretty good through all the run thrus.
I sucked it up. I tensed up - "wound up the spring" and waited for "action!"
"Action" was called and I bolted like a gun had gone off. I looked ahead in the hopes that I could keep up with Mickey. He wasn't there. I looked back. There he was, waddling along as best he could, at about 20% speed of what we had rehearsed and I could see the sweat forming on his brow.
I burst in laughter. I couldn't stop laughing - the focus puller caught the laughter bug too and fell off the dolly. The camera operator couldn't see what was going on around him and just kept shooting. There was no video assist so the director didn't know what was going on either.
On the pull back both me and the focus puller were laughing so hard that we tripped over each other and fell down. The Op just followed the puck until they called cut.
Mickey just kept on going to his trailer as he had a date with a horse. The op and director were happy with the shot... and the movie still plays every Christmas to this day.
