Don't bother with wikipedia, its never a good source of info as it can be totlay wrong at times. This is due to the fact that people and not researchers enter the data into Wikipedia.

Use IMDB, this is the Internet Movie DataBase and it holds a lot of information about everything to do with movies. So if you are looking for a reference for an actor or a movie/tv show, them visit IMDB.

LOL I sound like an advert for it...
