Some directors are known for working with the same actors multiple times, and "Superman" writer/director James Gunn is definitely one of those filmmakers. So it should come as little surprise that at least three "Guardians of the Galaxy" actors make cameos in the upcoming "Superman".

Opinion is sharply divided as to how high the superhero pic can fly when it hits theaters, with some suggesting a much lower range of $90 million to $120 million.

An early "Superman" teaser shot was mocked online for its depiction of the hero's flight. James Gunn said the shot "kind of got by" him.
