Eliza Dushku has landed a role on The Big Bang Theory.

The former Dollhouse star will appear on an episode of the CBS sitcom - which premieres its new season on a new night today! - as an FBI agent who conducts a background check on Wolowitz because he requires clearance for a new project.

Dushku isn't the only beauty set to appear on The Big Bang Theory this season. Katee Sackhoff will reprise her role later this fall, as well.
