'Chuck' enters the matrix with Carrie-Anne Moss

carrie-anne-moss-gi.jpg "Chuck" has cast a love interest for Adam Baldwin's character, and she should be more than up to the task of keeping pace with John Casey.

"The Matrix" star Carrie-Anne Moss has signed on for a multi-episode run on the NBC series' final season, EW reports. She's the second big guest star to join Season 5 of the show; it was announced at Comic-Con that Mark Hamill will appear in the season premiere.

Moss will play a character named Gertrude Verbanski, who despite her ungainly name is a ruthlessly efficient spy. She runs a private firm that competes with Chuck ( Zachary Levi) and Sarah's ( Yvonne Strahovski) newly launched enterprise.

Gertrude also has a history with Casey, and though they've been professional rivals they have clicked personally. That sound you may have just heard is a bunch of "Chuck" fans squee-ing.

In addition to the "Matrix" trilogy, Moss' credits include "Memento," "Disturbia" and the upcoming "Silent Hill: Revelation." Earlier this year she starred in a Lifetime pilot called "Normal," but it didn't go forward.

"Chuck" begins its final season on NBC Friday, Oct. 21.
