Oh boy, what A Cute One this is. Casting against type, An Invisible Sign sees Jessica Alba as a quirky/autistic, reclusive mathematics whiz (as represented by her having pigtails, because thick glasses just felt TOO real) forced out of her shell when she's given a job teaching math at an elementary school, where she meets a handsome young science teacher (Chris Messina) who is somehow able to overlook her eccentricities to see the FHM's 2007 Sexiest Woman in the World underneath.
