Megastar Rajinikanth twisted his ankle while shooting for ace adventurer Bear Grylls's Man vs Wild show at the Bandipur Tiger Reserve on Tuesday, forest officials said.
"Rajinikanth lost his balance, twisted his ankle and suffered minor bruises to his hand below the elbow," a forest official said.
"The actor is okay now," he added.
Meanwhile, the actor left Mysore and reached Chennai late on Tuesday.
Speaking to reporters at Chennai, he said he had suffered the bruises due to thorns, apparently at the shooting spot in Bandipur.
The forest department put a lot of conditions while permitting the shooting such as filming at own risk and not allowing the crew to use explosives and inflammable materials, according to officials.
Rajinikanth is the second Indian high profile figure to appear in Man Vs Wild after Prime Minister Narendra Modi.
A forest department official said the shooting started on Tuesday and would go on till the afternoon of January 30.
After the first day's shoot on Tuesday, the crew left the venue and would be back on Wednesday morning, he said.
