TNT and TBS have taken dips into the pilot-casting pool, adding several actors to three different projects.

At TNT, Christina Moore ("90210") and David Julian Hirsh ("Leap Years," "Naked Josh") have joined Jada Pinkett Smith in "Time Heals," and Conor O'Farrell ("CSI") will star opposite William Fichtner and Sherry Stringfield in "Night and Day," according to The Hollywood Reporter.

TBS, meanwhile, has beefed up the cast of its Valerie Bertinelli comedy pilot, adding Nadia Dajani ("Ned and Stacey"), Kevin Schmidt and Dean Collins.

"Time Heals" stars Pinkett Smith (who's also executive producing) as a selfless nursing director at a Charlotte hospital. Moore, who has a recurring role on "90210" as Naomi's (Annalynne McCord) mom, and Hirsh will both play nurses; Hirsh's character will also harbor a crush on Moore's character.

In "Night and Day," O'Farrell will play the head of a federal task force for whom Fichtner's ATF agent works. O'Farrell has a recurring role on "CSI" as Undersheriff McKeen and has also appeared on "Medium" and "The Unit."

TBS' comedy, created by Dave Caplan ("The Drew Carey Show"), centers on Bertinelli's character, a single mom who runs a lumber business while raising two teenagers. Schmidt ("The Young and the Restless") will play her son, while the previously cast Juliette Goglia will be her daughter.

Dajani, who co-starred in ABC's "Emily's Reasons Why Not" a couple seasons back, will play Bertinelli's next-door neighbor. Collins ("The War at Home") will play a friend of Schmidt's character.
