Where You've Seen Her Before: As Sierra, one of the reprogrammable people on Joss Whedon's "Dollhouse."

Breakout Role: Tani Tumrenjack, native of the island that Andre Braugher's submarine commander declares himself the dictator of.

Why: This is speculation based more on past performance than anything Lachman does in the "Last Resort" pilot, where the bulk of the action takes place either on the sub or back in Washington. I'm assuming she'll get much more to do in ensuing episodes, and based on the talent and versatility she displayed on "Dollhouse" — where many fans of that show suggested she made the premise much more believable than star Eliza Dushku — I'm also assuming she'll deliver when called upon by Shawn Ryan and Karl Karl Gajdusek.
