A 1950 movie titled "Champagne For Caesar," in which Ronald
Colman plays a walking encyclopedia who wins big on a quiz
show, lists KTTV in its credits. The reason: the fictional
quiz show on which Colman's character appears is on CBS, and
apparently the quiz-show scenes were filmed at KTTV's studios.
If they weren't, KTTV cooperated with the producers in some way.
(BTW, Art Linkletter plays the host of the show and does a
fairly decent acting job.) Also, two early (real) CBS variety
shows, one with Ed Wynn, the other with Alan Young of Mr. Ed
fame, originated at KTTV (Wynn's show in 1949, Young's in 1950).
