Similarities of the Time Travel concept with another movie

[sp. sot.]

Hello Griffin782002 here:
 
Yesterday, a T.V. channel in my country broadcasted a movie which made me to think that J.K.R. might have taken the idea of time travel from this particular film.
Well, the movie was 'The twelve monkeys'. I have watched a couple of times before, but I haven't made any considerations before the release of the P.o.A. movie. 
In this film the main character is send to the past in order to prevent the spread of a lethal virus that forced the sirvivors to live underground.The character has a memory about a person being murdered in a airport from the time when he was younger. In the beginning, because of mistakes, he and his partners end up in wrong dates. Later a researcher refers to these events as proper historical events. And in the end, it is proved that the person that he is witnessing being killed as a boy is himself while he is trying to stop the person who was responsible for the spread  of this particular virus. I wish to point out that in any other movie, with some recent exeptions, there is no such things, as far as I know. 
Well, what do you think?  : -)
