Nicolas Cage stands as one of the few action stars who rarely bothers showing off a hulking physique, like say, Arnold Schwarzenegger or Sylvester Stallone did in their primes (and in Stallones case, quite often these days too). Still, occasionally the roles he takes will ask for his wise-cracking character to actually produce evidence of muscle mass, so Cage, rather than hit the gym in preparation, just decided to let the visual effects wizards who proved themselves oh-so-competent with the rest of the films CGI touch up his abs and make him look buff. In fact, thats probably why the rest of the CGI in the film looks so crappy; they wasted so much time making it look like Cage actually put any effort into the role. To be fair, his physique is about as convincing as it gets.
