“Makes me think of the flick, “Damnation Alley”, from 1977...
It came out the same year as “Star Wars”, and had twice the budget.”

According to Aubrey Solomon, Twentieth Century Fox: A Corporate and Financial History, Scarecrow Press, 1989 p 258 (at least that’s the Wikipedia citation) the movie’s budget was $8,000,000. Star Wars (1977) budget was at least $11,000,000. https://tinyurl.com/ybl6eeej
