Johnny Carson Special Looks at His Legendary Career

We're getting a whole new look at NBC legend Johnny Carson on the 50th anniversary of his taking over as host of The Tonight Show.

The new PBS documentary details Carson's love/hate relationship with sidekick Ed McMahon, who was almost fired at least twice because Carson thought McMahon was trying to upstage him.

The rare clips were chosen from over 4,000 Tonight Shows that Carson personally preserved in a salt mine in Kansas, 45 stories underground.

American Masters Johnny Carson: King of Late Night premieres Monday, May 14 at 9pm on PBS.
