Great films spotlight events in people's lives, so it is no wonder that there a slew of bachelor party movies. Bachelor parties are an iconic day of male bonding that demand a vow of secrecy from everyone involved. Film gives storytellers a way to peel back that curtain, letting everyone see the debauchery and mayhem that can occur when men too old to party like uninhibited teenagers gather together for a night of partying like uninhibited teenagers. Hollywood bachelor parties are filled with dead porn stars, live tigers and numerous donkeys, because Hollywood bachelor parties tend to turn bad quickly.

"The Hangover" (2009)

When "The Hangover" hit theaters in 2009, the world of rated R comedies was forever changed. "The Hangover" wasn't just a bachelor film, it was an over-the-top event film of epic proportions. It created a formula so impressive that a second film amped up the drama by switching the baby to a monkey and moving from Las Vegas to Thailand because, hey, why wouldn't these idiots go bigger next time? The second film was the biggest rated R comedy ever and a third, slated for 2013, is expected to continue the gold mine. "The Hangover" made stars of almost everyone that touched it. No matter how many times we see it, the world will constantly want to see Mike Tyson drop Zach Galifianakis.

"The Best Man" (1999)

Hollywood, like most industries, is filled with nepotism, so it was little surprise when director Spike Lee's cousin, Malcolm Lee, became a director. What was a surprise was how well he did with his first writing/directing job, "The Best Man". Most well-known for Terrence Howard's breakout role, "The Best Man" won a number of awards and cemented the director as an artist in his own right. Featuring Taye Diggs, Nia Long, Morris Chestnut and Harold Perrineau, the film is fun but maintains a PG-13 rating to stay family friendly.

"Clerks 2" (2006)

When "Clerks 2" premiered at the Cannes film festival, the audience stood and pounded their hands together for eight minutes for the festival's longest ever standing ovation. In retrospect, that was probably due to the atmosphere because the movie wasn't quite that good, but it was still one hell of a bachelor party movie. Between Rosario Dawson's explicit revelation and an unorthodox donkey show (are there donkey shows of the orthodox variety?), "Clerks 2" brings more raunch and less dire peril to bachelor party movies than is standard, but that doesn't make it less enjoyable.

"Very Bad Things" (1998)

Peter Berg made a surprising choice replacing Vince Vaughn with Christian Slater as Jon Favreau's sidekick when he cast this cult favorite, but it couldn't have worked out better. Cameron Diaz plays the bossy, high-strung wife-to-be and Jeremy Piven adds his brand of aggressive, charged mania to the table as a groomsman. A prostitute, played by adult film star Kobe Tai, dies during the bachelor party, and a string of bodies follow. What sounds like a worn out trope instead turns out to be a wonderful and very dark comedy that has become a favorite to many.

"Bachelor Party" (1984)

If there are bachelor party films that came before this one, few people care. It may not have invented the genre, but it certainly proved the mass appeal. Suspiciously absent from the film's trailer is the famous donkey that crashes the party. Tawny Kitaen began to illuminate the 80s with her role. Tom Hanks may have been the star, but Bachelor Party broke comedy boundaries by featuring a suitable raunchy bachelorette party alongside the men's carousing.
