Several attempts to adapt the novel into a film or miniseries have been made with varying levels of success. Director Stanley Kubrick expressed interest in the 1960s, but collaborated with Clarke on "" (1968) instead. The novel's theme of transcendent evolution also appears in Clarke's "Space Odyssey" series. In 1997, the BBC produced a two-hour radio dramatization of "Childhood's End" that was adapted by Tony Mulholland. The Syfy Channel produced a three-part, four-hour television miniseries of "Childhood's End", which was broadcast on December 14–16, 2015.
