CORRECTION: I'd earlier said Elwes was playing Steve Trevor. My error, as pointed out by a commenter below. Here's the correct info:
Cary Elwes, star of "The Princess Bride" will appear as CEO of Themyscira Industries — the company owned by Diana Prince/Wonder Woman in the upcoming Wonder Woman TV pilot.
Adrianne Palicki ("Friday Night Lights") will play the Amazon princess and Elizabeth Hurley has been cast as villainess Veronica Cale, a recurring character.
