10 Movies That Made You Most Question Your Own Reality

6. Eternal Sunshine Of The Spotless Mind (2004)

What is it with people messing with their memories in films? Eternal Sunshine of the Spotless Mind follows an estranged couple who erased their memories of each other to cope with a painful break up. Despite having no recollection of each other, the two still find themselves drawn together after the procedure. As the protagonists memories are erased, we experience each of them in reverse, from the beginning of the couples relationship to the end. Who would have thought a romantic sci-fi set in Jim Carrey's head would work so well? Michel Gondry's movie has developed a cult following since its initial release and to date, it is one of the most fascinating explorations of memory committed to film. If a stranger walks up to you and claims that you've both been in a long term relationship that you've just forgotten about, don't instantly freak out and call the police. You may have just 'Eternal Sunshine'd' them.
