Newbie looking or a (hopefully) simple regex

[RonMarz]

I'm looking for an expression that'll filter out any header that has, say, the terms "Superman" and "zip" in it, whether it's something like "Superman 199.zip" or "The Adventures of Superman 3000.zip."

I've been gnawing on this all night and haven't come up with anything that works.
