There is the movie Maneaters of Kumaon on Utube, link below.
It's okay but like many movies based on books, they don't provide the same 'feel' as the book does.

I'm sure everyone of us that reads Corbett's books has a different imagination in our minds of what the country, people and animals are like from Jim's writing. A movie is only one interpretation that we all see and hear and for many this bursts their bubble of imagination, mine definitely.
