Bigfoot 1970 Written and directed by Robert F Slatzer.
A pilot parachutes from her conked out plane only to kidnapped by a Bigfoot in need of a woman to keep his species going. That's Joi Lansing on the left, she's the pilot. The other lady is Judy Jordan, she plays the girlfriend of a biker. The gals are in trouble, the local Bigfoot tribe have kidnapped them for breeding purposes. Or lunch, it's not clear yet.
John Carradine and his business partner John Mitchum are traveling through the same area in search of customers. John M is the younger brother of Robert Mitchum. The biker who's gal was taken by Bigfoot is played by Christopher Mitchum, he's Robert Mitchum's son. Bing Crosby's son Lindsay plays one of the bikers and Doodles Weaver is a forest ranger.
None of them can do much with the dialog, the story or the budget. It's lacking in all respects. The director is lacking a Wikipedia page, his IMDb page lists two feature films and a documentary on John Wayne. I've seen Slatzer's 1968 film The Hellcats. It was a MST3K selection that I saw when it originally aired, I watched it more recently, 2015, when I worked my way through one of those 50 Movie Packs. I gave that The Hellcats a 2.
Bigfoot is about 50% better so I gave it a 3. Still poor. You can watch it at the link above, though why you would...
