I'm a Celebrity, Get Me Out of Here! (2003)

Based on the successful British TV show of the same name, so-called "celebrities" leave behind their pampered lives for weeks of roughing it in a remote outpost of the inhospitable Australian rainforest. The celebrities live out in the open, sleeping on makeshift cots in primitive conditions and trading their gourmet meals for rice, beans and water. Viewers vote, by phone and Internet, to keep their favorite contestant in the camp; the one receiving the least number of votes each night is forced to leave. The lone, remaining celebrity at the end of the trial emerges as the King or Queen of the Jungle.
