Funnyman Ben Stiller is following in the footsteps of his pal Will Ferrell - he's signed up to appear alongside British adventurer Bear Grylls in an upcoming episode of his Man Vs. Wild series.

Ferrell spent 48 hours in the frozen Swedish wilderness learning how to stay alive against the odds with the former military survival expert, and even drank his own urine - a regular survival tip from Grylls on his hit show.

And Ferrell's experiences convinced the Zoolander star to sign up for a similar challenge - he's set to feature in an upcoming episode later this year.
