Currently Zardoz is it for me but I think that "Dünyayı Kurtaran Adam" aka Turkish Star Wars might just take the cake.
Minutes after pulling themselves out of the ground, storm troopers on horseback charge. A massive karate fight breaks out, and you can say what you want about their effects, sets, costumes, acting ability, sound editing and lack of continuity, but damn, Turkish people can fight. Luke and Han take out 15 men on horses with flips and kicks in super fast motion while the Indiana Jones theme plays. Periodically, the music abruptly stops and they show a half-second clip of a giant-headed papier-mâché mask somewhere else screaming “YAAAGGHHH!” Please believe me when I tell you that this was never explained at any point during the rest of the movie.
My next best guess is that they’re hit by lasers since they both fall down when a man in armor shows up. Turkish special effects are not what you’d call an exact art, and here the picture is severely scratched up, which I think indicates a failed attempt at scratching a laser-like beam onto the film itself. They’re captured and taken to a cruel gladiator arena where Darth Vader’s water cooler robot proves its evilness by swinging a screaming child around by its neck. Luke and Han watch for what seriously has to be three solid minutes of noisy kid dangling before they start another karate fight. Darth Vader comes out of a cave, and as soon as he does, most of the rest of the scene is viewed through the eyeholes of his helmet, including shots of Darth Vader himself. This could have been another massively insane mistake by the Turkish production crew, but I like to think it was a profound metaphor about how karate fights make Darth Vader take a careful look at himself, through the evil-shaped helmet eyeholes in his mind. - Seanbaby
