90210

As previously reported, Jason Priestley will direct the 18th episode of The CW's 90210, scheduled to air in March.

The actor, and Beverly Hills, 90210 alum, teased the episode's plot in a recent interview with E! Online.

He said the installment is "very ambitious, production wise," as a large-scale disaster may be heading for the world's most famous ZIP code. Priestley added: "I have a lot of challenges ahead of me on how to shoot this, it's big."

So, will there be victims as a result of the disaster?

"Yeah, we're in a hospital...a female ends up in the hospital," Priestley said, adding that the event will NOT include Adrianna giving birth.
