A late soviet science fiction film, with some Star Wars elements, and some Mad Max elements.

From Wikipedia:

The Witches Cave (Russian: Подземелье ведьм) is a 1989 science fantasy film from Gorky Film Studio, USSR and Barrandov Studios, Czechoslovakia.

The script was written by Kir Bulychov based upon his own story and directed by Yuri Moroz. The cast featured Sergei Zhigunov as Andrei Bruce, Marina Levtova as Belogurochka, Dmitry Pevtsov as Oktin Khash and Nikolai Karachentsov as cosmolinguist Jean. The movie had two nominations in 1991 Nika Awards.

I believe sharing this film, which is not commercially available within the United States, is protected under fair use for the purpose of criticism.
