Movie: The Avengers
Release date: May 4

After its 200 million-dollar opening weekend, The Avengers has definitely sent the execs behind the rest of the summer movies into sudden panic attacks. The same goes for actresses having to follow Scarlett Johansson's surprisingly substantial ass-kicking role as the deceptively sexy Black Widow.

Johansson doesn't simply serve as eye-candy in a tight jumpsuit in the film. Rather, she recruits the Hulk (Mark Ruffalo), manipulates the supervillain Loki (Tom Hiddleston) and manages to stay alive during the massive war that erupts in New York with only a gun and martial arts moves at her disposal.
