As ''The Blind Side'' rakes in mega-bucks, we take a look back at the star's greatest on-screen moments, from ''Speed'' to ''The Proposal''
THE BLIND SIDE (2009)
Bullock broke out of her rom-com comfort zone for this based-on-a-true-story flick about football and family. The triumph of Bullock's performance is that she manages to be both big-hearted and hard-charging most notably when she goes looking for Michael (the football player she's taken in) and faces down group of local thugs. ''You threaten my son, you threaten me,'' she growls. And taking on Leigh Anne is not a good idea. She's got a ''Saturday night special'' tucked inside her designer handbag.
