What's the difference between Peter Fork in and Peter Fork as?

Have you heard of Columbo or Peter Fork? It's American drama and he was an actor.I love this drama.This drama has a lot of stories. When I watch these dramas,I noticed that I can see this phrase 'Peter Fork in' at the begging of the drama,but after a stories I can see 'Peter Fork as'
Would you tell me what the difference is between Peter Fork in and Peter Fork as?
