"Looper" is informed by, and pays a kind of respectful homage to, those pictures, and it's also got some precedent in the no-budget sci-fi indie " Primer ."
With Looper, the borrowings are no less obvious, whether in the plotting (recent sci-fi mind-fuckers like Primer and Timecrimes vie with elements of noir and Bad Seed–style bad toddler behavior), the settings (the dystopian city of the future is drawn from countless cinematic models), or specific touches (the hired thugs in 2072 dress like spaghetti western bandits).
It was both a comfort and a concern to learn Shane Carruth of Primer fame had assisted Johnson in figuring out the mechanics of time travel here; a comfort because Primer is one of the finest time travel features ever made (and on a shoestring, no less), and a concern because it requires dozens of watches to totally unpack.
(This wouldn't have been the worst crime; you might have ended up with a new Primer, the absorbing 2004 indie from Shane Carruth, who reportedly assisted Johnson with some of Looper's time-travel elements .)
Primer, the 2004 cult item adored by geeks and ignored by most everyone else, seemed to take that as its subject, unveiling a wholly different, dizzyingly complicated way of looking at the problem.
Looper has new ideas in a genre that hasn’t had any since the 2004 indie time-travel movie Primer.
