She's been pretty quiet since Studio 60 on the Sunset Strip was cancelled, but never fear: In addition to starring in the big-screen adaptation of Frank Miller's The Spirit, Paulson will also be getting into patients' heads as Dr. Claire Allen on Cupid. Just point us to the couch, doc.

This Irish-born actress has garnered attention (and award nominations) for her work in film and TV across the pond. Now, she makes her stateside debut in CBS' Harper's Island, as one of several wedding attendees who tries to survive a visit to the island while others get picked off one-by-one. So much for the honeymoon.

She's popped up on 7th Heaven and played Ruby on Supernatural, but she's also set to play Lucy Ewing in the planned film version of Dallas. That is, if she can survive as the blushing bride on Harper's Island.

This hottie from Down Under had a recurring role on Season 4 of Everwood and on the short-lived Fox series, Vanished, before busting on to the big screen in Eragon. Now, you can see Egan really shine in a lead role as the dashing war hero David Shepherd in NBC's Kings.

Sebastian has a small part in the critically acclaimed Rachel Getting Married, but TV fans will remember him from his stint as one of Serena's old flames, Carter Bazien, on Gossip Girl.

This lovely lady appeared in several guest spots on shows including Desperate Housewives and Boston Legal before snagging the role as the 17-year-old version of "Scarlett" in Zac Effron's new comedy 17 Again. She's headed back to the small screen as King Silas' beautiful and brainy daughter Michelle on Kings.

This striking redhead had a small role in Walk Hard: The Dewey Cox Story before landing the enviable role as Nathan Fillion's responsible, no-nonsense daughter on Castle. We bet she'll have fun trying to keep him in line all season.
