Already taped for a June airdate, Ferrell spent 48 hours in the frozen Swedish wilderness learning how to stay alive against the odds with the former military survival expert.
In the episode, Ferrell will be shown drinking his own urine — a regular survival tip from Grylls on his hit show.
Grylls tells Variety he was impressed with his movie-star survival pal: “He trusted me when it mattered and we survived.”
Land of the Lost star Ferrell adds the trip was the “thrill of a lifetime, even though I did get urine-drunk, which is sad.”
