"The Night America Trembled" is a television dramatization of the public reaction to the 1938 radio broadcast of "The War of the Worlds" that aired September 9, 1957, as an episode of the CBS series Westinghouse Studio One.

In spite of many pre-broadcast promotions describing the play, and several statements during the program itself, the 1938 broadcast, which featured simulated news reports, was taken seriously by a number of listeners, who thought an actual Martian invasion of Earth was taking place, and reacted in a doomsday fashion.

Orson Welles's lines from that night were split up among a few different people, including one of the announcers, and the only person to break the "fourth wall" and speak to the audience was host and veteran CBS news reporter Edward R. Murrow.

[2] The courts ruled against Welles, who was found to have abandoned any rights to the script for "The War of the Worlds" after it was published in Hadley Cantril's 1940 book, The Invasion from Mars: A Study in the Psychology of Panic, in which Howard E. Koch is listed as sole author.

It starred Paul Shenar as Orson Welles; other cast members included Vic Morrow, Michael Constantine, Eileen Brennan, Tom Bosley, John Ritter, and Meredith Baxter.
