If there's one thing you can count on when you see a Tom Cruise franchise action movie, it's the look on his face. It is cool and poised, sleek and alert; it's all dashing resolve. But during "The Mummy," I kept looking at Cruise and having a strange sensation, which is that the emotion those familiar features seemed to be radiating was, in a word, confusion. Throughout the movie, he looked a little slack and a little blank, a little what-the-heck-is-going-on? It could, theoretically, have been an element of Cruise's performance. His character, a tomb raider named Nick Morton, gets invaded by the spirit of an Egyptian mummy; his soul then becomes a battleground between good and evil (at least, that's the idea).
