Les Maîtres du temps (lit. The Masters of Time, a.k.a. Time Masters, Az idő urai in Hungarian) is a 1982 Franco-Hungarian animated science fiction feature film directed by René Laloux and designed by Mœbius. It is based on the 1958 science fiction novel L'Orphelin de Perdide (The Orphan of Perdide) by Stefan Wul. The film centres around a boy, Piel, who is stranded on Perdide, a desert planet where giant killer hornets live. He awaits rescue by the space pilot Jaffar, the exiled prince Matton, his sister Belle and Jaffar's old friend Silbad who are trying to reach Perdide and save Piel before it is too late.
The BBC (who were co-producers) aired an English-language dubbed version in 1987 and 1991 called Time Masters, featuring, amongst others, the voice of Ray Brooks, famous for being the narrator of Mr. Benn.
Directed by René Laloux, the film was produced largely at the PannóniaFilm studios in Hungary. The visual design was based on the art of Mœbius, otherwise known as Jean Giraud.
The motion picture story is based on the novel L'Orphelin de Perdide (1958) by the French writer Stefan Wul.
In the original novel, the character of Piel was also named Claude, like his father. Laloux changed this to distinguish father and son.
