The Comic-Book Character: The long-suffering love interest of Bruce Banner aka The Incredible Hulk.
The Movie Version: A cameo, as the Avengers' activities draws Betty's attention to Bruce's current whereabouts, and they share a few tender moments in between the mayhem.
Played By: Given that Mark Ruffalo has replaced Edward Norton, Liv Tyler would provide some much-needed continuity with the earlier film.

The Movie Version: Effectively working as a spy, Moondragon is the person who gives the Avengers the lowdown on HYDRA's plans and initiates the action.
Played By: A hairless Naomi Watts would provide the necessary gravitas.

Rather handily, she can make any man become her slave simply by kissing him with her enchanted lips.

Played By: Evan Rachel Wood
