On an episode of Seinfeld, Kramer and Mickey are "stand ins" for a soap opera........?

Question

I am wondering what the point of that is.

Answer 1

I didn't see the episode, but in general, a stand-in is hired to take the place of the actor for technical purposes. The actor will perform the scene, while a camera assistant marks the actor's places on the floor, with tape. Stand-ins then re-enact the scene, moving from place to place for the lighting, the cameras, the measuring of distances, etc., for the director to determine his/her camera shots, until the scene is actually ready to be filmed/taped.
On many shows, Little People are hired to stand-in for child actors who are permitted only a limited work schedule, based on their age, and will rehearse the scene for the child all day until it's ready to be shot.
Since stand-ins are generally hired based on their height and similar coloring (compared to the actors), they may also be used occasionally as body doubles.
Hope this helps with your question.

Answer 2

No point! But isn't that what Seinfeld is all about?

Answer 3

No answer for you but that's the "he took it out" episode, one of my favorites! God, I miss that show!
