Do you follow actor film history

Have you ever watched, or tried to, a whole actors filmography, because of one movie, or appearance in a television show. There actors that it is easy to to, eg James Dean, that with the exception of very few television appearances which have been used in one or other documentary only made 3 films. Then there are actors like Michael Caine, who has a more then a 100, that is more difficult. Then actors like Will Smith who have huge summer blockbusters that even though not doing it on purpose you end up watching most of his movies without realizing it. A while back some friends and I decided to print out some of the actors we like and admire and then mark down all the movies, shows etc we had seen them in and it was fun at how much/little we did see. So how about you? Ever done something like that, and if so how did it go, any favourites?
