WHEN NATURE CALLS is a wilderness adventure comedy from the Troma stable. It sees an ordinary city-dwelling family heading into the great outdoors for some fun adventures, but if you like this kind of humour then you'd be better off watching the John Candy comedy THE GREAT OUTDOORS. As a Troma film, this is quite terrible: a general barrage of unfunny jokes made on a very low budget indeed. If you like watching bad actors pretending to interact with stock wildlife footage then perhaps you'll enjoy it more than I did.
