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.
