Very Bad Things (1998)

Storyline:

The only thing that Kyle Fisher wants is to marry the woman he loves, Laura Garrety. All Laura wants is the wedding of her dreams. But before Kyle staggers down the aisle with his beautiful, controlling bride, his buddies decide to give their friend one last night of freedom, male bonding and debauchery. Real estate hustler Boyd (Christian Slater); the battling Berkow brothers, Adam and Michael; and introvert mechanic Moore throw a Las Vegas bachelor party for Kyle that is a smashing success, with plenty of booze and drugs - and even a visit from a lithe young stripper. But accidents will happen...
