Piers Morgan, who will be taking over Larry King's hour on CNN in January, appeared on 'The Situation Room' (weekday, 6 PM ET on CNN) and talked to Wolf Blitzer about replacing King and why he wants his new show to be "dangerous."

"Following Larry is bit like following Frank Sinatra," Morgan said. "But I can do things my way, and by dangerous I kind of mean I like interviews to be theatrical. I like it to be a theater, where two protagonists come in and we have fun and it's probing and challenging, a little bit edgy perhaps, and occasional dangerous, where no one is quite sure what's going to happen next."

Morgan added that Larry King's long-running interview show was also occasionally dangerous:

"Some of Larry's most memorable moments encompassed extreme danger, for instance when Marlon Brando kissed him live on air."

Of course, what really made 'Larry King Live' dangerous -- particularly in its later years -- was the impression the audience got that the host could quite possibly fall asleep at any moment. Which is a dramatic tension that Morgan, 45, will struggle to recreate.
