How I Met Your Mother

The How I Met Your Mother guest-starring list continues to grow.

Amanda Peet will appear on a January episode of the sitcom. The actress was recently seen in the movie 2012 and last starred on the small screen in the short-lived series Studio 60 on the Sunset Strip.

On the installment, titled "Jenkins," Peet will portray a co-worker of Marshall's.

She's one of a number of big names set to appear on the sitcom, as Chris Elliot will appear on this week's episode; and Rachel Bilson, Tim Gunn and Stacy Keibler are slated for the 100th installment in January.
