More than 150 lions are freed and 70 are injured: this is the most dangerous film ever filmed. Roar was filmed primarily at Africa USA, an animal enclosure outside Acton, California, which later became the Shambles Big Cat Sanctuary.

The film, which was produced at a cost of 17 million dollars, only managed to rake in 2 million dollars at the box office. The goal was to create a family-friendly film, a light-hearted and informative adventure comedy. Unfortunately, What happened during the filming was completely contrary to the intention of the film.
