The first time I really noticed him was in "Die Hard".

I think that's the first time anyone really noticed him. I think "Die Hard" was a great movie, made so both by Willis and Rickman. It's amazing to me how different Willis's character is in that one from most action movies since (including the sequals), and Rickman made such an impression on me that afterwards I tried to see every movie I could with him in it.

I'll still take Douglas Adams, but Rickman is great, even in movies I don't really like.
