The Committee for the First Amendment was an action group formed in September 1947 by actors in support of the Hollywood Ten during the hearings of the House Un-American Activities Committee. It was founded by screenwriter Philip Dunne, actress Myrna Loy, and film directors John Huston and William Wyler.
Other members included Lucille Ball, Humphrey Bogart, Lauren Bacall, Jules Buck, Joseph Cotten, Dorothy Dandridge, Bette Davis, Melvyn Douglas, Henry Fonda, John Garfield, Judy Garland, Ira Gershwin, June Havoc, Sterling Hayden, Paul Henreid, Katharine Hepburn, Lena Horne, Marsha Hunt, Danny Kaye, Gene Kelly, Evelyn Keyes, Burt Lancaster, Groucho Marx, Burgess Meredith, Vincente Minnelli, Edward G. Robinson, Robert Ryan, Frank Sinatra, Kay Thompson, Billy Wilder, and Jane Wyatt.
On October 27, 1947, members of the group flew to Washington, D.C., to protest HUAC hearings. Their involvement was ineffective, and membership in this group came to be regarded with suspicion. Ira Gershwin, for one, was called before the California anti-Communist Tenney Committee, and was asked to explain his participation.
