Duper
James Gunn is better known for mixing quirky humor with standard-issue superhero shenanigans in Guardians of the Galaxy (2014). The movie (which for the record I liked) was actually watered-down Gunn for the PG crowd, a fairly risky move (A gun-toting raccoon? A walking tree with only one line?) that paid off handsomely to the tune of $770 million worldwide.
Super made four years earlier hews closer to authentic adult-dosage Gunn. Frank Darbo (Rainn Wilson) is a short-order cook and longtime loser who has experienced only two perfect moments in his life so far: his marriage to former junkie Sarah (Liv Tyler) and his helping a police officer catch a purse thief--both moments immortalized in colored-pencil drawings that he tapes to a wall. Sarah soon leaves him for Jacques (Kevin Bacon), a local strip club owner and mid-level dealer who lures her away with offers to renew and maintain her habit.
