The 1981 film Roar may not be the best movie ever made — but it is without doubt one of the most unforgettable, both in terms of what appears onscreen and the story behind those images. Directed by first-time filmmaker Noel Marshall, this extraordinary project found Marshall, his wife Tippi Hedren, stepdaughter Melanie Griffith, and other family members playing characters who regularly interact with an array of wild animals, including lions and tigers. The behind-the-scenes twist? They actors and crew actually did shoot in close proximity to these creatures with the result that more than 70 people were injured during the movie’s lengthy production, including future Speed director Jan de Bont, who required more than 120 stitches after a lion ripped off his scalp.
At 10 p.m. ET on June 24, Animal Planet is premiering a documentary called Roar: The Most Dangerous Movie Ever Made which details this extraordinary story. Watch an exclusive clip from that film, above.
