I like this show! Let's face it. Grey's Anatomy is dying, and The Deep End is Grey's Anatomy (the early years, that is), only with lawyers. It's got plenty of snappy dialogue, romantic sparks, inter-office power struggles, handsome people in nice clothes, office sex, Black-Eyed Peas tunes and cupcakes! What's not to love?

The cast of ABC's 'The Deep End' gathered to talk about power mad bosses, bonding over BBQ, and who the biggest bloodsuckers are: vampires or lawyers.

Billy Zane, Matt Long, Tina Majorino, Leah Pipes, Mehcad Brooks and Ben Lawson sat down for our cameras to answer fan questions about how 'The Deep End' is different from other lawyer shows.

Television's legal drama waters will soon be teeming with new sharks when ABC's 'The Deep End' premieres on Jan. 21.

Billy Zane stars as one of the firm's top partners, with Matt Long, Leah Pipes, Tina Majorino, Ben Lawson and Mehcad Brooks rounding out the cast as the associates. On Tue., Jan. 12, we'll be interviewing them about the show with your questions.
