A design must be conceived, drawn, lit and then rendered. The difference is that your desktop PC can render a simple animation, while the lighting, colouration and detail necessary to make animated characters of scenes in movies look real takes considerably more rendering power.

Shy, retiring modern guy Fletch (Corden) is under the thumb of his bitchy girlfriend. His comic sidekick mate Jimmy (Horne) talks him into going on a hiking holiday to get away from it all, so they pierce the dark, eerie woods near a rural town straight out of An American Werewolf in London, complete with a pub full of grizzled, socially backward locals who know of a terrible curse that’s befallen the village centuries ago.

So the pair take flight to find a hometown that feels right, calling on friends and relatives around North America in a series of vignettes that teach them how not to be good parents. Between the goofy, talky soccer mum (Janney) to the extreme Aquarian hippie (Gyllenhaal), the two end up more confused than they started.
