Comedy legend Carl Reiner knows a thing or two about late night: he's the only man on the planet to have appeared on every incarnation of the "Tonight Show," from Steve Allen to Jimmy Fallon.
And with all the changes going on in late night TV, Reiner is very optimistic. While he calls Fallon an "amazing talent," Reiner especially likes the newest name in late night, James Corden, host of the "Late Late Show" on CBS.
"He's unbelievable," said Reiner. "He sings, he dances... he is very graceful and he sings beautifully."
