The Hangover Red Band Trailer (2009)

The red band trailer for The Hangover.

Two days before his wedding, Doug and his three friends drive to Las Vegas for a blow-out bachelor party they'll never forget. But, in fact, when the three groomsmen wake up the next morning, they can't remember a thing. For some reason, they find a tiger in the bathroom and a six-month-old baby in the closet of their suite at Caesars Palace. The one thing they can't find is Doug. With no clue as to what transpired and little time to spare, the trio must retrace their hazy steps and all their bad decisions in order to figure out where things went wrong and hopefully get Doug back to L.A. in time to walk down the aisle.

Mike Tyson agreed to appear in The Hangover because he liked the directors work. In real life, he owns not one but seven tigers.

While Bradley Cooper might play a hard drinking guy in this movie, he is actually a teetotal.

Lindsay Lohan was offered the part of the stripper, but turned it down because she thought the film would flop. She was very wrong; The Hangover took over $467 million at the worldwide box office.

Showing confidence in the franchise, plans for a sequel (The Hangover Part II), were already in motion before this move hit theaters.

On paper, The Hangover reads like another of those bromance road-trip movies; four guys go on a bachelor party to Vegas, and when they wake up in the morning the groom is missing, but they've acquired a tiger and a baby.

However, The Hangover is anything but formulaic. It's fresh, it's funny, and it has a great cast who all prove their comedic abilities. The Hangover is full of gags, but it does also have a plot, and it's a great one at that. You can't help but feel sorry for these guys, who have inadvertently lost the groom, and though they make every possible effort to find him and get home, everything just goes from bad to worse for them.

As Phil, Bradley Cooper is the one who attempts to hold this misfit group together, but he's also the hardest drinker of the lot. Zack Galifianakis plays Alan, the unruly wild child who can't be tamed, and I defy anyone not to feel sorry for Ed Helms' Stu Price.

There are so many funny moments that it's hard to pick a few to highlight, but Ken Jeong absolutely steals every scene he is in. I love his work anyway, but he really goes to town in this film, and it's obvious that he really enjoyed making this movie.

As you will have guessed from this red band trailer, those who are easily offended might be best to stay away but for the rest of us, who know all too well what waking up with the hangover from hell can be like, this film has it all.
