Eva Marie Saint Talks (Briefly) About "Superman" Sequel
OK, so it's nothing all that shocking: Ms. Saint reported that she had indeed signed on for a Part 2, although she has no idea who the villain might be. She also mentioned that her character might hang out a bit with Lois Lane and her super-kid, but beyond that the actress either doesn't know ... or cannot say.
The (allegedly) $270 million "Superman Returns" grossed about $391 million in worldwide box office last summer. Producers were obviously expecting a bigger hit, but they weren't so disappointed as to cancel the sequel plans. More on "S2" when it becomes available.
