And does anyone think it's funny that while The Magnificent Seven was a re-interpretation of The Seven Samurai, Kurosawa's Ran was a reinterpretation of Shakespeare's King Lear?
And Yojimbo was an uncredited rip-off of Dashiell Hammett's novel Red Harvest. Bruce Willis later remade it as Last Man Standing. However, aside from getting the period correct, it had even less to do with the novel than Yojimbo.
I don't think it's really fair to mention remakes of films that were originally books. The Planet Of The Apes remake was so much worse than the original, but that was a book first, so I can't really count it. The only exception is Psycho, because that was a shot-for-shot remake. Honestly, I can't even imagine how that one got okayed.
For bad remakes, I'd go with Godzilla, The Haunting (although that might have been a book), the 70s King Kong, and there was a really, really bad remake of The Cabinet Of Dr. Caligari from 1962. I caught it on AMC, TCM, or FMC. It has absolutely nothing to do with the original.
And, while I haven't seen I, Spy, from what I've heard about, I'd add it to the list. Thunderbirds and Get Carter are supposed to be terrible, too.
