10 Most Delayed Films Ever

Tippi Hedren convinced her husband, Noel Marshall, to make a movie about big cats living in the wild with her as the lead star. After Marshall wrote the script for Roar, he predicted the shoot would take six months. Instead, it took 11 years!

So, what went wrong? Well, let's just say that everyone involved drastically underestimated how dangerous wild animals are. One of the stars, Melanie Griffith, was mauled by a lion so badly, she needed plastic surgery.

A lion sank its teeth into the cinematographer's skull so deeply, a surgeon had to literally sew his scalp back on. Marshall was attacked so many times, he developed gangrene, forcing production to shut down for years. Hedren broke her leg after an elephant hurled her from its back and she was bitten by a lioness so badly, she required 38 stitches.

Eight years into production, a dam burst open, washing away most of the set and killing several animals. Somehow, Marshall managed to complete the film and released it in 1981. The film may have tanked at the box office but it also inspired the incredibly entertaining documentary, Roar: The Most Dangerous Movie Ever Made, which details the film's nightmarish production.
