Oasis of the Zombies (L'Abîme des Morts-Vivants) is a 1982 film by director Jesús Franco for French producer Marius Lesoeur.
The plot involves treasure hunters who track down a lost fortune in Nazi gold in the desert, only to discover that the treasure is still guarded by the Afrika Korps soldiers transporting it, who have become zombies.
Franco filmed a "Spanish version" simultaneously with the French version (under the title La tumba de los Muertos Vivientes), probably to placate Lina Romay (since the French producer had chosen other actors to be in the "real version"). Only the director's cut (the Spanish version) includes scenes with Lina Romay and Eduardo Fajardo, but that version has never been released outside of Spain.
