Roar is a 1981 American adventure comedy exploitation film written and directed by Noel Marshall, produced by and starring Marshall and his then-wife, Tippi Hedren, and co-starring Hedren's daughter, Melanie Griffith, and Marshall's sons, John and Jerry. The film follows a man living with lions and big cats in Africa; when his family attempts to visit him, they are accidentally left alone with multiple animals that they fear.
The idea for the film was conceived when Hedren and Marshall learned about endangered wildlife while Hedren was filming Satan's Harvest in Mozambique. The two, alongside their family, prepared for the film by living with lions in their home. Filming started in California during the 1970s. A flood from a dam destroyed the set and equipment three years into filming. After numerous such problems arose on-set, the budget increased drastically and production was delayed for over 11 years. Roar also became notorious for the dangerous situations that the cast and crew were placed in, which resulted in 70 people, including the stars, being injured during filming by the predatory animals used in the film. The actors sustained many life-threatening injuries ranging from bone fractures to scalpings and gangrene. Much of the footage capturing the injuries were included in the final cut of the film. It has been considered the most dangerous film shoot in history.
The film was released theatrically in Europe in 1981 but was a financial failure. It was released theatrically in the United States for the first time on April 17, 2015. Hedren established the Shambala Preserve after the film was released, and co-wrote the 1985 book Cats of Shambala about her experience of filming Roar.
