In the trailer, Grylls is heard calling Rajinikanth, 'Raji' and together the two wade through a river, climb across a bridge and brave through all sorts of obstacles at the Bandipur Tiger Reserve in Bengaluru India.

"You want me to climb this?" questions Rajinikanth, at one point, as the two stand at the bottom of a very steep area.

Later in the trailer, Grylls is heard telling Rajinikanth, "You ARE a superhero!"

Many fans of the star, who is fondly referred to as Thailaiva or 'leader' in Tamil, are eagerly waiting to watch the full episode which will air on 23 March on Discovery.

Other than the trailer, Discovery Channel India also initiated a dance challenge called 'The #ThalaivaOnDiscovery Challenge'.
