The Hangover (2009)

The Hangover trailer is for Todd Phillips' 2009 comedy about the bachelor party from hell. Two days before his wedding, Doug drives to Las Vegas with his best friends, Phil, a schoolteacher played by Bradley Cooper, Stu, a nervous dentist played by Ed Helms, and his odd future brother-in-law, Alan, played by Zach Galifianakis. The next morning, the three friends wake up in their trashed Caesars Palace suite with no memory of the night. There is a tiger in the bathroom, a baby in the closet, Stu is missing a tooth, and Doug is gone. To find him before the wedding, they retrace the night step by step, running into a stripper, played by Heather Graham, and the gangster Mr. Chow, played by Ken Jeong. Mike Tyson appears as himself. It is available on Blu-ray and digital.
