Frank Grillo is one of the few Superman actors to have technically appeared in the new DCU prior to James Gunn's big reboot movie, having voiced his character Rick Flag, Sr. in Creature Commandos, which launched the new DC Universe. But in Superman, his appearance is just a bit different, leaving fans wondering why the film missed a simple touch like making Grillo's hair the same color in the movie as in the animated series.
As it turns out, it's all down to Grillo having to film another show at the same time he was appearing in Superman, requiring him to keep his hair dark. Still, the actor predicts they'll get it right in his next appearance.
