Ralph Block on AllMovie

American writer/producer Ralph Block started out at the Pathe studios in 1928, functioning as producer or associate producer for five of that studio's earliest talkies. Block moved on to Fox, where he labored away on the George O'Brien western series. By 1934, he was one of the staffers at Warner Bros. He curtailed his writing activities in the-mid 1930s to devote himself to the newly formed Screen Writers Guild, serving as that organization's first president. He was later active in such politically volatile concerns as the Hollywood Writers Mobilization and the Motion Picture Democratic Committee. Ralph Block's well-documented liberalism caused him no end of trouble in the 1950s, when he fell victim to the Hollywood blacklist; his last screen credit was the 1950 Jane Powell musical Nancy Goes to Rio (1950).
