I've been a fan of Denis Leary's work ever since I saw Ted Demme's 1994 film "The Ref," which is an EXTREMELY underrated black comedy about a bickering couple taken hostage by a harmless thief around Christmas.
Leary was hilarious in the film and I made an effort to track down some of his other efforts. A lot of his film output hasn't been so great (the one with Sandra Bullock - "Two If By Sea" - is okay at best), but his stand-up still rocks.
"Lock N' Load" is a scathingly offensive attack on everything in sight: life, politics, alcohol, cigarettes, coffee, religion, sex, kids, family, etc...
Leary has put on a few pounds since "The Ref" (looking a bit on the chubby side) which led me to believe this was only filmed recently - however I was surprised to find it had been filmed almost a decade ago! Some of the parts are simply hysterical and it proves, if nothing else, that Denis Leary is one of the funniest men in the world.
