I haven't read Jeff Smith's RASL, but I love BONE to ribbons. BONE's one of those great comic works that you can put right next to WATCHMEN, MAUS, and THE DARK KNIGHT RETURNS. I'll definitely have to check RASL out, and it looks like it may be coming to the screen soon in the future, according to Deadline.
RASL is about a former scientist who by the use of a immersion suit can leap into other parallel universes, and steals art from those universes for various clients. He is chased across those universes by assassins working for the Compound, who want their tech back. Parallel universes haven't been explored much in film, and this sounds like a good comic to adapt.
Lionel Wigram, who produced the SHERLOCK HOLMES films for Warner Brothers, will be producing this project, along with Smith and Peter Eskelsen as executive producers. With Jeff Smith directly involved, maybe some day we'll get a BONE movie in the future? Those books are so epic, though, and so specifically drawn, that I'm not sure a live-action BONE film would be right. But RASL has the potential to be a terrific take on sci-fi noir.
