I shot Slim Jim commercials for 3 years in a row. We would run the camera at 6.25 frames per second, (a quarter of it's normal speed). The actor would move at quarter speed as well, when the result is played back at normal speed, you get in sync dialog with manic actors movements.
The first Slim Jim added more complexity by having 7 versions of the same character fighting amongst himselve. Heavy use of a motion control camera, a metronome and a choreographer in an all blue suit helped to make the fight sequence work.
The final Slim Jim like the others was set inside the stomach of someone who has just eaten a Slim Jim.
Jim wants out and uses an angle grinder to escape, into an operating theatre.
The second Slim Jim went aquatic, only one actor to deal with this time but water always complicates matters.
The set was built in a tank at Shepperton studios and could be flooded and emptied at the Directors command. The focus puller, camera grip and myself wore dry suits for most of the shoot. The walls of the set were made from Neoprene.
