2. The Hangover Part II (2011) The Whole Of The Hangover (2009)
A bit of a cheeky one this, but lets face it, the sequel to 2009s surprise sleeper hit, The Hangover (featuring the clever title: The Hangover Part II) didnt exactly win prizes for originality. In fact, if you were to metaphorically lay them on top of one another and hold them up to the light, youd see that they are basically the same movie, from plot and structure, right down to the smallest set-pieces. Indeed, its lucky the producers cant sue themselves for plagiarising their own material. In fact, come to think of it, maybe there was a mix up in pre-production and someone accidently reprinted the script for the first movie, instead of the second one and yes, such accusations are highly facetious, and obviously not strictly correct
