Green Lantern/Castle meets Tony Stark

The Avengers market machine is really kicking into high gear now. Monday night’s episode of Castle on ABC saw Robert Downey Jr and Nathan Fillion doing a little product placement together instead of the usual “Next week on Castle…” promo. It’s not half bad.

Of course, Nathan Fillion should have pointed out that he’s Green Lantern to have really had a shot at one-upmanship.
