In case you doubted that Noah Wyle was One Of Us, he told us at SDCC that he proudly owned a Doctor Who scarf as a teenager. He also told us the best method of killing Falling Skies' alien invaders.

Oh, and there are spoilers for Falling Skies below.

We'd heard years ago that Wyle's mom knitted him a Doctor Who scarf when he was a teenager, and apparently it's true. He still has it, and he might pass it along to his seven-year-old kid when he's a bit older. This seven-year-old hasn't been introduced to Doctor Who yet, which means he's about three years too old to start discovering the show.

Wyle has been putting his alien-fighting chops to good use, starring in Steven Spielberg's new series Falling Skies. We really liked the preview we sat at Comic Con, and Wyle seemed really excited about it too. He described his character: Tom Mason, a former history professor from Boston University, who's "very familiar with battle strategy and tactics. He teaches predominantly American history, so he teaches the American Revolution. And it's that belief, that there's historical precedent for a small, committed group of resistance forces being able to repel a larger invading force that I think allows him to maintain a pocket of hope."

Wyle stressed that this show deals with tough issues, but retains hope. The aliens knocked the human race back to nineteenth century levels of technology. "We basically have to construct society all over again. There are no rules. There's no law, military or otherwise. So how do you maintain a large group of people — 100 fighters, 200 civilians — and what are the rights of each?... So it's not just the conflict of trying to figure out how to fight the aliens. It's the trying to figure out how to bring very disparate, very desperate people together for a common [goal]." And the group can only move as fast as its slowest civilian, so there's a lot of debate over whether the herd should be thinned for a greater good.

This show isn't as dark as Battlestar Galactica, or as bleak as The Road, says Wyle. Nor is it as slick as V. It's somewhere in the middle — a compelling human drama against a science fiction backdrop.

Off-camera, Wyle described to us the method of killing one of these aliens, who are multi-limbed and huge. You have to get in really close and strike, in order to kill one of them. We asked him if he's managed to kill any of these fearsome opponents so far, and he gave us a conspiratorial smile: "I've bagged a couple."

We also talked to Moon Bloodgood, who plays a former pediatrician who's entrusted with looking after the children and the other civilians, plus patching up the fighters when they return from missions against the alien occupying force. She said it's a really different thing, not being so action-oriented, but she's enjoying getting to explore her character's emotions more. She's playing more of a maternal character this time around. "Not being seen in such a tough-girl role, you get to delve more into my emotions versus my physicality."

The survivors have gone "back to basics" and lost all communications with other parts of the country, so they're just hearing rumors about what's happening in other areas, with the fight against the aliens.

And she said the aliens look really unique and terrifying, and they're sort of a mixture of CG and practical effects. "I think they're frightening. They did a really good job. You never know with TV CGI what it's going to be. You can't just pull out your staple alien creature, you really have to scare people."
