I've seen the movie several times. In Italian, the title was translated simply as Mato Grosso, which makes it oddly geographically specific. ¯\_(ツ)_/¯
Connery definitely starred in even weirder movies. Have you seen Zardoz?

Oh, yes! Just once, but Connery, in just underpants and boots, battling some surreal head-shaped apparitions, is something I won't ever forget. I have no idea what the plot was about - but that's OK, because I had no idea about that either during or just after watching :D
A movie so bad it's kind of good - though second-hand embarrassment (at the performances, effects, plot, characters) was a bit hard to bear at points.
