Films

In the mid-1930s, Hull pursued a screen career.^[3] He made his screen debut in 1934 for Educational Pictures, a short-subject studio. He co-starred opposite singer Sylvia Froos in the Young Romance series of musical comedies filmed in New York; Hull often joined Froos in song. In 1935 Hull was signed to a contract by Warner Bros., and spent the next few years playing leading men both in dramas and musicals.

When his Warners contract expired, Hull had no trouble finding work at other studios. He teamed with Patricia Ellis, one of his leading ladies at Warners, for the Republic Pictures musical Rhythm in the Clouds (1937). He also played romantic leads in a string of features for Monogram Pictures. Two of Hull's better-known appearances of this period were opposite Boris Karloff, in The Walking Dead (1936) and Night Key (1937). Some of Hull's early appearances have him billed as "J. Warren Hull."

In 1938, Columbia Pictures terminated its association with the Weiss Brothers, independent producers who had been making adventure serials for Columbia release, and decided to make its own cliffhangers. Warren Hull was signed for Columbia's second (and perhaps best) serial production, The Spider's Web (1938), based on a popular magazine character. Hull played three parts: criminologist Richard Wentworth, his masked-and-caped alter ego The Spider, and, in a second masquerade, lowlife mobster Blinky McQuade. The personable Hull brought a breezy sense of humor to his serial roles; he is probably the only serial hero who ever laughs on screen. Hull kept audiences following the Spider's thrilling exploits, making The Spider's Web the most popular and profitable serial of the year, outstripping such worthy cliffhangers as Buck Rogers and Dick Tracy Returns by a wide margin, according to a tally published in the Motion Picture Herald and The Film Daily.^[4]

Pleased with Hull's performance, Columbia cast him as Mandrake the Magician in its 1939 serial. Universal Pictures starred the now-established serial hero in The Green Hornet Strikes Again! (1941) and Columbia put him back in the mask and cloak for The Spider Returns (1941).

Radio and television

In the mid-1940s, Hull returned to radio announcing, appearing with frequency on such programs as Your Hit Parade and Vox Pop. During World War II, Hull traveled about the country and in Canada, putting on Vox Pop before servicemen at camps and bases.^[5] After the War, he did Vox Pop broadcasts from France, Britain, Alaska, and Puerto Rico. In 1947, he hosted The Warren Hull Show, for CBS radio. During this time, Hull also hosted Cavalcade of Bands for Dumont radio.

In 1948 he replaced Todd Russell as the host of the radio game show Strike It Rich. Hull continued as host when the show was adapted for television in 1951.^[3] This is the TV series for which Warren Hull is best known; Hull remained host for the duration of the series, which ended in 1958.

Hull was also the emcee of Spin to Win, only the second game show created by the team of Mark Goodson and Bill Todman. In 1953–54, former Miss America Bess Myerson co-hosted a game show called "The Big Payoff"; Hull occasionally substituted for regular co-host Robert Paige. During the next two decades he hosted TV programs such as Top Dollar, Beat the Odds, and Public Prosecutor. By the early 1960s, Hull was largely retired and was living in Virginia Beach, Virginia. In 1962, he came out of retirement to host the game show Who in the World.^[6]
