Watch Piers Morgan's CNN Debut

Larry King's replacement appeared on ‘The Situation Room’ Thursday.

Piers Morgan made his CNN debut Thursday night.

Appearing on Wolf Blitzer’s The Situation Room, Larry King's replacement talked the royal wedding, the World Cup, Wikileaks and his upcoming talk show.

Morgan called King "The great legendary television interviewer" and "one of my all-time heroes."

"I like it to be a theater where two protagonists come in and we have fun and it's probing and it's challenging, a little bit edgy perhaps and occasionally dangerous, where no one quite knows what's going to happen next," he added.

Piers Morgan Tonight kicks off in January.
