Based on the comic book by Ed Brubaker.

Tom Cruise and Sam Raimi are loosely attached to star and produce.

I haven't yet read Sleeper (though I've heard great things about it), so I don't know if it qualifies as a "superhero" book (descriptions make it sound more like the spy thriller genre), but since the characters have superhuman abilities, and it's set in the Wildstorm Universe I'm putting it here.
