I have not seen all of his movies but the ones I did see he was always a pleasure to watch. The man is totally lovable in everything he stars in.
My favorite movies are: The Fourth Protocol, Mr. Destiny, Noises off, Shiner, The Italian Job, Victory, Zulu and California Suite.

1) The Cider House Rules
Michael Caine as Dr Wilbur Larch
was wön Academy Award for Best Actör in Supporting Role =)
2) The Dark Knight My Favöurite.!

I love those movies too! I guess I just love anything he's in! lol! But I do think he makes a great Alfred in the Batman movies :)

The Italian Job

I can't say I have seen a bad performance of him yet. Even in the 'bad' movies he starred in, his part was always worth watching.
Oh and I forgot to add some more favorites of mine which are Ashanti and The Man Who Would Be King.
