UPDATE: Another little juicy morsel of season four news … two words: Baby Awesome.

September 20, the premiere date for Chuck‘s fourth season, is still more than a month away, but we have the first season four trailer to tide us over:

Whatcha think? Linda Hamilton, who’ll play Chuck and Ellie’s mama, is teased in the clip, but we’ll also have guest gigs from Lou Ferrigno, Harry Dean Stanton, Dolph Lundgren and Nicole Richie (who returns as Sarah’s high school nemesis-turned-spy rival Heather) to look forward to. Think it’s gonna be another fun season with Chuck and pals.
