Have you ever wondered what would happen if you travel back in time and kill your grandmother before she will give you the birth? Right, you will never be born. That means you will never travel back in time and never will kill you grandmother. That's called "Time Paradox" or "Grandfather Paradox". There are lots of theories explicating why the paradox can be avoided. By the way there is quite exotic one: "Can-Not Because Has-Not" that presumes that no one has invented the time machine in the future, because if it'll happen we have had already knew this due to existence of arriving time travelers from the future. But how it is connected with Looper, the movie filmed by Rian Johnson in 2012? The answer is: very straight. In not-so-near future, in the year 2042, a mob hitman makes money by successfully assassinating human targets arriving from more distant future. Everything goes smoothly before he receives the new target: himself arriving from 2072… Now you understand why we had to begin with "Time Paradox". However, such a twisted storyline is only one crucial driving force of Looper. The brilliant cast is the second. A mob killer, Joe, is portrayed by two actors, and each of them is a big name in Hollywood scoreboard. The younger version of Joe is represented by Joseph Gordon-Levitt while the older one is played by Bruce Willis. If such a star cast, picturing one only character is not enough for you, we are glad to let you know about other names: Emily Blunt (The Adjustment Bureau, Young Victoria) Piper Perabo (Covert Affairs , Ashes, Carriers ) and Paul Dano (Being Flynn, Cowboys & Aliens). And after all of that, have any doubts if this film worth your time?
