Casting Bits: Morena Baccarin Heads to 'The Good Wife', Another Gilbert on 'The Vampire Diaries'
Another round of casting bits, then? Tonight, we have lots, including a new mystery character on Once Upon A Time, a Buffy alum heading to Grimm, and two athletes taking a trip to Hawaii. But let's begin in a courthouse...

Morena Baccarin is headed to The Good Wife: the Homeland (and V, and Firefly) star will appear in a March episode of the CBS drama as a high-powered executive who accuses Colin Sweeney (a returning Dylan Baker) of sexual harassment, Entertainment Weekly reports. This isn't Baccarin's only stop while Homeland's on break: she's returning to another CBS drama, The Mentalist, this April.

Also heading to The Good Wife: The Big C's Nadia Dajani has signed on as Sara, one of Will's (Josh Charles) sisters who happens to be so bossy she decides to find him a new girlfriend. (Ack, Alicia, no!) TVLine reports that Dajani's role will be a recurring one.

The Vampire Diaries
 says hello to another Gilbert:
 newcomer Lindsey R. Garrett joins the CW series as Samantha Gilbert, according to TV Guide. But she won't be crossing paths with Elena (Nina Dobrev) any time soon, as Samantha's only appearing in flashbacks: she will appear in "1912", an episode airing this February that revolves around the older Gilberts interacting with the Salvatores.

Sebastian Stan enters a fairy tale: the Gossip Girl star is headed to ABC's Once Upon A Time, TV Guide reports. Not much is known about who he'll play, but he's expected to appear in late March or early April. Stan also recently appeared alongside Chris Evans in the film Captain America.

Sticking with the Upper East Side, Blair Waldorf's mom tries to get Tom Selleck: Gossip Girl's Margaret Colin is headed to CBS' Blue Bloodsaccording to TV Guide. She'll play an investigative reporter who's been keeping a secret long-distance relationship with Frank (Tom Selleck) -- but the secret threatens to unravel when he has to track a bad guy going after his love. The two previously appeared together in the film Three Men and a Baby. The episode will air this March.

Colin Hanks gets personal on Happy Endings: the Dexter killer will appear the ABC comedy as, well, himself. Entertainment Weekly reports that Hanks will be a new celebrity friend of Dave's (Zachary Knighton), thanks to his food truck becoming some sort of nightlife hot spot. His episode is slated to air later this season.

Azura Skye is getting Grimm: the Buffy alum (remember her as Cassie Newton, she who predicted her own death in the show's seventh season?) will appear in an upcoming episode of NBC's Grimm, according to TV Guide. She'll play Robin Steinkeller, a B&B owner who also happens to be a Seltenvogel, a bird-like creature, who seeks Nick's (David Giuntoli) help. Her episode has yet to receive an air date.

Tia Carrere dances her way to In Plain Sight: TV Guide reports that the Celebrity Apprentice contestant (and one-time Dancing with the Stars celeb) is joining the USA drama's final season as Stan's (Paul Ben-Victor) dance instructor slash lover.

Speaking of Dancing with the Stars, season 4 winner and Olympic skater Apolo Anton Ohno is headed to Hawaii Five-0: the athlete confirmed the news himself on Twitter. Also appearing on the show is Philadelphia Phillies outfielder (and native Hawaiian) Shane Victorino.

Steve Buscemi pulls off 30 Rock double-duty: the Boardwalk Empire star returns to the NBC comedy as detective Len Wosniak on its February 16 episode, according to EW. He's also directing the episode, which sees Jack (Alec Baldwin) using his police connections to form what Tina Fey calls "a private police force ... protecting the rich." It ought to be an experiment, at least.

Finally, Justin Hartley is headed to Hart of Dixie: the Smallville star (and recent Castle bad guy) will attempt to woo Zoe (Rachel Bilson) in the February 6 episode, according to TVLine. Also headed to the CW drama, as we reported earlier: American Idol winner Scotty McCreery, who'll provide the soundtrack to a Zoe/George (Scott Porter) conversation.

I told you there's a lot of them tonight.
