The original Boondock Saints was relegated to video store shelves before most would-be fans had an inkling it had passed them by in theaters. But eventually, chances are one night a friend would suggest watching this weird, violent movie about hot twin brothers with a serious gun fetish, Catholic complex, and Latin tattoos, and you'd pass the word along. Basically, Murphy MacManus (Norman Reedus) and Connor MacManus (Sean Patrick Flanery) were blue-collar Irish guys who decided that they'd had enough of the scum on the streets and began wiping them out in various creative ways, although their favorite weapons were and remain the gun. Their buddy Rocco, a mob errand boy, was the de facto third Saint. Meanwhile, they're being tracked by a very odd FBI agent by the name of Paul Smecker (Willem Dafoe in a fabulously bizarre performance) and three bumbling local cops. And then there's Il Duce (Billy Connolly), the infamous assassin who's finally paroled from prison.
Ten years later, the Saints are in Ireland with Il Duce, aka their dad, when the word comes that someone in Boston killed a priest they knew and tried to make it look like the Saints did it. Game on. The boys shed their woolly sweaters and their long hair and beards and return to Boston.
