Who is Maria in the movie?
Maria is played by Kelly Jo Minter. The reason she appears in the ending credits, I think, is because she originally had a speaking part (she does in the book), but they cut a lot of scenes including Marias speaking part. You can spot her in a few scenes in the movie. One is at night, when the Lost Boys saunter into Maxs video store. Paul says, We only come here to watch one thing, and if you look quickly you can see Maria on the right side of the screen. She also appears in the scene where Lucy is calling Michael to ask him to stay with Sam while she goes out with Max. You can see Maria over Lucys shoulder, repeatedly looking at Lucy with a teasing smile on her face.
