Keeping track of an actor’s career

I am wondering if there are any websites on the internet where you can look up an actor and find out everything they have been in or had any involvement with. I am always seeing actors on television or in the movies and knowing that I have seen them in something else, but I can never remember where. I want to be able to look it up so it will stop bugging me. Recently I saw Randy Charach in something and I know I saw him in something a long time ago when he was younger, but I can’t remember what.
