Sarah Michelle Gellar
Then: Buffy Summers, Buffy, the Vampire Slayer
Now: Bridget and Siobhan, Ringer

Ringer is full of action, but this time it's not Gellar pulling the punches (and brandishing a stake). Instead, it's Gellar who's doing most of the running, when she plays two sisters trying to get away from their dangerous and complicated lives. Of the twins, the independent, jaded Bridget is slightly closer to Buffy than spoiled Siobhan, but both girls are a far cry from Gellar's TV past.
