America's Next Top Model
CW, Feb. 20, 8 p.m. ET

Launching its 10th season, Tyra Banks's Top Model does not disappoint. A winningly silly free-for-all of catfights, fashion and camp, it makes Project Runway look like an academic conference. But there are a couple of significant developments: Twiggy is gone from the judges' panel. Replacing her, model Paulina Porizkova sweeps in imperiously and makes merciless assessments of the girls. (She thaws later.) And one contestant, Fatima, has a heartbreaking history: As a child in Somalia, she was genitally mutilated. However, she's as high-handed a diva as any of 'em.

Glau, 26, is all geared up about playing a good android on FOX's Terminator: The Sarah Connor Chronicles.

YOU DON'T LOOK LETHALLY STRONG. I danced full time, but then I got hurt so I changed to acting. I never imagined doing heavy action roles but I'm loving it! I get teased, though. The first thing my sister said when I was cast was, "Now you've got to come up with a bad-ass catchphrase!"

HOW DID YOU PREP? Terminator boot camp! It's not what people think. [I learned] how to move without having any human tics and tendencies. For me, [the challenge] was sitting down but never crossing my legs or arms. Never adjusting my clothes. A Terminator just wouldn't. We also went to the shooting range.

ARE YOU A GUNSLINGER YET? I'm pretty good! I bought some books [beforehand], because I didn't want the prop guys to think I was just a stupid girl who didn't know how to use [guns]. They're complicated!
