He may be shooting a new "Mission: Impossible" flick, but the only guns on set with Tom Cruise yesterday were his arms.
Cruise was spotted showing off his muscles while filming "Ghost Protocol" in Vancouver -- and they've certainly been getting a workout, as Tom has been doing a lot of his own stunts for the movie.
Though they traveled with him to Prague for filming in September, Katie Holmes and Suri weren't on set this week -- Katie's been shooting her new movie with Adam Sandler in L.A.
