I've been a fan of Alan Rickman (Snape) & Gary Oldman for a long time.

go see
Robin Hood Prince of Thieves (Alan Rickman)
and
My Immortal Beloved (Gary Oldman).

Alan Rickman plays the evil sherriff. brilliant evil tantrums in this one!!!
Gary Oldman plays Ludvig von Beethoven. the depth, the hurt, the frustration and the underlying passion. simply wonderful.
