It took a good many tries to get Hunter S. Thompson's 1971 novel Fear and Loathing in Las Vegas to the screen; Ralph Bakshi even once tried to get an animated version off the ground. Even the attempt that finally made it out in 1998 hit a few potholes on the way. Bruce Robinson was originally approached to direct, but refused. Then Alex Cox was hired, but stars Johnny Depp and Benecio del Toro weren't happy with his vision. Finally, Terry Gilliam came on board, and, quite honestly, I can't imagine the film working without Gilliam's particular style.
