Actor-producer John Abraham, who has been named the new face of Nation Geographic channel, has unveiled a new campaign called 'Unlock'.

The campaign is all about openning the mind and thinking beyond the restriction. During the press conference, John said that he would raise the topics like homosexual and remarriages to make people think out of the box.

The 40-year old actor, who loves adventures, said that he is pleased to get associated with the campaign. He also said that it's a proud moment for him as he is a big fan of National Geographic 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," John said during the event, according to Press Trust of India.

"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," he added.

Keertan Adyanthaya, director of NGC and FOX International, was also present during the event. Adyanthaya said that the actor's association would add extra panache to the channel.

"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 told DNA.
