The sequel The Boondock Saints II: All Saints Day was released in 2009.
If you can believe it, it has been 20 years since The Boondock Saints was released in 1999, introducing MacManus brothers Connor (Sean Patrick Flanery) and Murphy (Norman Reedus).
It seems like we should get a sequel every 10 years, so now that it’s 2019 maybe Flandus can update fans with news on the long-awaited third movie?
