4. Though she won an Emmy for her role as Skyler White (Anna Gunn), was battling a mystery illness during filming. "I was actually ill while I was filming the show and it affected my weight," she says. "They gave me cortisone and I puffed up and gained weight. Now I'm better, thank God."

5. Aaron got a concussion while filming a fight scene with Raymond Cruz, who played Tuco. "The next thing I know I guess I blacked out and I woke up to a flashlight in our eyes and it was our medic," says Paul.

6. Walt & Jesse's blue meth is actually crystallized sugar, AKA rock candy.
