Amanda Peet, one star who certainly doesn’t need any immediate services of a Plano dentist at the moment, and who is one of the stars of 2012, last week’s box-office-topping disaster film that sank to a distant third place behind New Moon this weekend, has been confirmed as a guest star on How I Met Your Mother this season; her episode is scheduled for January.

Those blessed with long-term memory will recall that Peet got her start on the small screen, initially on The CW’s Jack and Jill series, and more prominently (and disastrously) three years ago on NBC’s ill-fated Studio 60 On the Sunset Strip.

While the guest appearance is a one-shot, Peet’s career has always had TV ties, even though she has fared better in her big-screen efforts overall.
