Grandfather Paradox (2014)

Chuck, a slacker genius, and Norris, his strait-laced best friend, make a bet one night about the legendary 'Grandfather Paradox', and what would happen if you went back in time & killed your own grandfather. But Norris is in for the shock of his life when Chuck invents a working time machine! Inspired by the great science-fiction comedies of the 1980s, 'Grandfather Paradox' is a quick snappy piece full of one liners and quirky humor.
