Roar: Lions of the Kalahari (2005)

It's survival of the fittest, the fastest and the fiercest in this striking IMAX wildlife adventure about a young rogue nomadic lion who invades the domain of an elder established king of the jungle and challenges him for pride supremacy at a strategic watering hole in the Kalahari Desert in Botswana. The documentary, a National Geographic production, was shot over two years by director Tim Liversedge, who also provided the stunning cinematography. Narrated by James Garrett.
