Zac Efron: "I’m a big fan of Bear Grylls"

Zac Efron has revealed that he is a big fan of British adventurer Bear Grylls.

The actor, who starred in the High School Musical franchise, admitted that the presenter and survival expert inspires him to spend more time in the great outdoors.

According to Showbiz Spy, he said: "I’m a big fan of Bear Grylls and Man vs. Wild.

"I like to backpack, filter my own water, make a fire. But I bring packaged food - I’m not setting squirrel traps.

"As soon as the days get longer and the sun hangs in the sky I feel more alive. I’ve fallen off just about everything it’s possible to fall off."

Efron stars in the upcoming film Charlie St Cloud, which is released in the UK on October 8.
