Despite its critical praise, Alex Gibney's Musk documentary about the world's richest man is ending its theatrical run after just two weeks, according to entertainment news site Showbiz411 .

Upon its release on Oct. 9th, Musk was shown in just four theatres in two cities nationwide, but that number rose to over 450 by the second (and ultimately final) week of its theatrical run, though the total take, according to Gizmodo , was a paltry $571,902, making it "an unmitigated flop."

But could there be something else at play here other than simple box office math?
