I'd have to nonconcur with the inclusion of Raiders Marion Ravenwood.  She was hardly helpless.  On the contrary, she's quite defiant and feisty.  Remember in the "Indy gets his ass kicked by the big German mechanic" scene, where she is inadvertently trapped inside the tail gunner turret on the plane?  Does she start screaming and beating on the canopy?  Hell no!  She cocks the machine gun and begins gunning down all the villains like a Weed Eater!
