3. JENNIFER CONNELLY AS JENNY BLAKELove interest: Cliff Secord a.k.a. The Rocketeer
Jenny Blake is an actress in Hollywood saved from Nazi kidnappers by a stunt pilot. It just so happens that said pilot is also a superhero, named The Rocketeer, who can fly with a top-secret jet pack that he randomly found. Even if the premise didn't exactly cause box-office figures to soar, Jennifer Connelly's presence was most definitely effective in causing other things to skyrocket.
