The film rights reverted in 1974, at which time the option was acquired by a French consortium led by Jean-Paul Gibon, with Alejandro Jodorowsky attached to direct. Jodorowsky proceeded to approach, among others, the progressive rock groups Pink Floyd and Magma for some of the music, Dan O'Bannon for the visual effects, and artists H. R. Giger, Jean Giraud and Chris Foss for set and character design. For the cast, Jodorowsky envisioned Salvador Dalí as the Emperor, Orson Welles as Baron Harkonnen, Mick Jagger as Feyd-Rautha, Udo Kier as Piter De Vries, David Carradine as Leto Atreides, his son, Brontis Jodorowsky, as Paul Atreides, and Gloria Swanson, among others. The project was ultimately scrapped for several reasons, largely because funding dried up when the project ballooned to a 10–14 hour epic.
