“Hope” springs eternal, or at least for a second season, at Fox.

Network announced Tuesday morning that it had renewed breakout comedy “Raising Hope” for a second season. Early renewal came a day after ABC picked up its signature comedies for fall.

“‘Raising Hope’ has emerged as a comedic standout: wickedly smart, hilarious and full of heart,” said Fox Entertainment prexy Kevin Reilly.

Greg Garcia created and exec produces “Hope,” which comes from 20th Century Fox TV. Lucas Neff, Martha Plimpton, Garret Dillahunt, Shannon Woodward and Cloris Leachman star.

Also on Tuesday, Fox kicked off its portion of the TV Critics Assn. press tour by announcing — as expected — a firm “preview” date for new epic prehistoric series “Terra Nova.” Show will get a two-night launch on Monday, May 23 at 9 p.m. and Tuesday, May 24 at 9 p.m. (behind the penultimate “American Idol”). The show then returns officially in the fall (following a similar air pattern to the launch of “Glee” in 2009).

And the network announced that its new sketch comedy series from Jamie Foxx, along with comedian Affion Crockett, will get a sneak preview on Thursday, March 31 at 9 p.m., behind “Idol.” Show will regularly air this summer on Thursdays at 9 p.m. starting June 9.

The as-yet untitled show comes from Fox TV Studios, Foxx/King Ent. and Tanatmount. Foxx, Todd Yasui, Marcus King, Jaime Rucker King, Eric Tannenbaum, Kim Tannenbaum and Mitch Hurwitz are exec producers.

Also, Fox announced that former “So You Think You Can Dance” judge Mary Murphy will return to the show, along side Nigel Lythgoe, this summer.
