Jesse Eisenberg has fought zombies, launched Facebook, worked at an amusement park and had a bomb strapped to his chest. Meanwhile, his quirky and often awkward mannerisms shine through both onscreen and off.
He's already built a career playing strange characters - but unlike other actors his age, he isn't known for romantic comedies or for his good looks. He's known for taking on a variety of unique roles and playing them well. I'm not sure what planet he would be from, but I'm sure he would make a great alien in a Men in Black film.
