"The Conqueror" has great production values. Apparently, everyone's favorite eccentric millionaire/filmmaker, Howard Hughes, thought this would be a smashing success. I recently watched "Genghis Khan" (1965) with Omar Sharif, and thought that film suffered from miscasting (James Mason as a Chinese for example). But that's nothing compared to the casting of John Wayne as the mongol warrior. Did anyone, even Hughes, ever think that was a good idea? Believe you me, this role was more than even the Duke could chew (apparently even Wayne later said he wasn't suited for the role). But it's not just Wayne's and the casting director's fault that the movie is a stinker. The dialogue is so bad it has to be seen (or heard) to be believed. Our great warrior hero Temujin/Genghis Khan (Wayne) shows all the intellect and charisma of a caveman ("I stole you. I will keep you. Before the sun sets you will come willingly to my arms!"). As an epic adventure, "The Conqueror" is really, really bad. But if you're looking for some campy entertainment, all of the flaws, the miscasting and ridiculous dialogue, could be regarded as qualities. It has some slow stretches where not much happens but "The Conqueror" certainly is offers quite a unique viewing experience. I'll let you decide if you think that's good or bad, for you.
