Jessica Alba as Sue Storm ("Fantastic Four")
Brilliant scientific breakthrough: Sue Storm, aka The Invisible Woman, can control light waves in a way that allows her to turn herself and others invisible. She can also do cool, complicated stuff with invisible energy.
Why we're unconvinced: Sue Storm was a brilliant scientist even before she gained super powers, and she has to say a lot of technical science words. Let's just say they don't exactly sound natural coming off Jessica Alba's tongue.
