No animals were harmed in the making of this movie. 70 members of the cast and crew were.
"Roar" was first released in 1981. It's now being re-released.
The film follows wildlife preservationist Hank (The Exorcist producer Noel Marshall in his sole and career-derailing turn as an actor and director), who lives harmoniously alongside a menagerie of over 100 untamed animals, including cheetahs, elephants, lions and tigers on a preservation in the African plains. When his wife and children arrive (real-life wife Tippi Hedren, The Birds, and step-daughter Melanie Griffith, Working Girl) for a visit, a long-brewing battle for dominance between the lions erupts and threatens their very lives.
Here's the trailer:
