Cape Fear

Robert De Niro paid a dentist $5,000 to make his teeth look suitably bad for the role of Max Cady. After filming, he paid $20,000 to have them fixed.

De Niro did a lot of working out several months before the movie and during the shoot to make him the muscular Max Cady, reportedly taking his body fat down to only 3%.

The climactic scene out in the swamp was filmed in John U. Lloyd State Park, in the middle of a mangrove swamp. A tropical depression set over the set for four days, so the film crew had to wait for the storm to stop, so that they could make their own rain.

Reese Witherspoon auditioned for the role of Danielle Bowden.

Robert De Niro's thick Max Cady accent reportedly gave Scorsese the creeps, and as a joke, De Niro would call the director's house, leaving messages as Cady.
