10 Movie Documentaries Better Than The Actual Movie

As much as the low-budget action thriller The Boondock Saints became a shockingly successful cult classic on home video, it was dumped in just five cinemas on its initial theatrical release and widely reviled by critics who felt that it was simply another "post-Tarantino" knock-off.

For a brief moment in time, writer-director Troy Duffy was considered to be the next big thing in Hollywood, with his script for The Boondock Saints making him an immediate - if fleeting - household name, as is depicted in this fascinating fly-on-the-wall documentary.

Overnight depicts Duffy as a man with a planet-sized ego whose absurdly arrogant attitude resulted in him effectively sabotaging his own career before it really got started.

Though the documentary was shot on Duffy's own insistence, ultimately filmmakers Tony Montana and Mark Brian Smith knew that there was no way to spin the footage in the director's favour.

And so, Overnight is a jaw-dropping depiction of unearned hubris in one of the world's most fickle industries, which makes it far more interesting than The Boondock Saints itself - which, somehow, received a Duffy-directed, critically panned sequel in 2009.
