Katey Sagal and Brad Garrett Are Heading to This Is Us

The NBC family drama centers on four adults whose lives are interconnected in various ways and features a stand-out cast that includes Milo Ventimiglia, Mandy Moore, Sterling K. Brown, Chrissy Metz and Justin Hartley.

The show's executive producers announced during the Television Critics Association fall previews on Tuesday that they are adding to that appeal with some A-list guest stars.

Katey Sagal (Sons of Anarchy) and Brad Garrett (Everybody Loves Raymond) will appear in the show's second episode as a high-powered agent and a television network president, respectively, who are both involved in the career of TV actor Kevin (Hartley).
