The 40-year-old "Madras Cafe" star, who is a fan of the channel's action-packed content, has also launched a new campaign 'Unlock' with the channel.
"I can hardly contain my excitement on being a part of the legacy that is National Geographic Channel. I have always been inspired by the yellow window and have followed National Geographic channel's (NGC) shows religiously.
"I am thrilled to represent the channel and be a part of its exciting journey with 'Unlock'. I look forward to take Nat Geo viewers through the various aspects of the campaign; encouraging them to unlock their minds along the way. I am grateful to NGC to have given me this opportunity and I am sure that the viewers and my audience will enjoy this collective journey," John said in a statement.
"John is known for an exciting brand of cinema and with his love for action, sports and knowledge; he aptly embodies the brand philosophy of National Geographic Channel. His attributes certainly add that extra panache to our channel, its programming and the 'Unlock' campaign," said Keertan Adyanthaya, Managing Director - NGC and FOX International Channels.
