Chris Rock would eat his own arm

Chris Rock would eat his own arm if he was stuck in the wilderness.

The US comedian - who voices Marty the Zebra in 'Madagascar: Escape 2 Africa' - admits he might be forced to turn to cannibalism if he ever found himself stranded.

When asked how he would cope in the jungle on his own, Chris told BANG Showbiz: "If I was by myself? I would start by eating my arm."

Ben Stiller, who portrays Alex the Lion in the movie, joked: "But then you'd bleed to death!"

Ben added he has picked up survival skills from US TV show 'Survivor', in which contestants are stranded on a desert island, and is confident he would be able to manage if he was lost in the wild.

He said: "I would remember everything I've seen on 'Survivor'. But really, I've never been stranded anywhere on my own and I really hope it never happens."

Jada Pinkett Smith, who voices Gloria the Hippo, says she has learned some handy survival tips from her husband Will Smith.

She said: "I've been married to Will for 11 years and he has taught me well, so I would do everything I could to survive - I would find shelter first."

In the sequel to 2005's hit animation 'Madagascar', Alex, Marty, Melman the hypochondriac giraffe and Gloria find themselves stranded in the beautiful plains of Africa.

Here, they encounter their own species for the first time and although they quickly settle into life in the wild, they soon begin to miss their Central Park home.

'Madagascar: Escape 2 Africa' is released in the US and across Europe from this month.
