How do I hide a character to another layer during animation?

How do I hide a character to another layer during animation? Version 2.48
I figured out how to do that with non-rigged objects that have Obipo names, but when I tried to hide the rigged character it does not hide. I have found that if it has a Actipo it does not work. I had already done some of the animation before I learned to change layers during animation. Please let me know.
Thanks,
Skipper

You can always animate the character to position itself behind the camera.
