The Scene: Phil (Cooper), Stu and Alan (Galifianakis) wake up the next morning in a dirty hotel in Bangkok sans Teddy (Lauren's brother, played by Mason Lee).
The Action: Down this alley, best reached by taxi, you can still find bird's nest soup or buy some Chinese red lanterns to deck out your home.
The Scene: The monkey's drug dealing intersection.
The Action: Last time we checked there weren't any Capuchin monkeys nickel-and-dime'ing in this 'hood near the river.
But it's a good place to sit and have a bowl of roadside guay tiow -- noodles -- as you imagine how location manager Somchai Sanitharangkun managed to close off all seven streets leading out from the one-tree roundabout for the filming.
The Scene: In an attempt to recall the missing night, the boys are led to the Chinese temple of Ching Mei to meditate, and Alan has a juvenile vision.
The Action: Self-proclaimed as the "world's largest outdoor museum," Muang Boran offers a Cliffsnotes-esque what's what of Thailand's architectural monuments.
A sala was added to create the temple atmosphere for the film near the existing Phra Kaew Pavilion, which, as an Ayuttayan representation for Buddhism, is a fitting place to calm the mind.
The Scene: At Siam Sam's Bar, things get a little crazy.
The Action: The colorful stretch of dubious nightlife that runs parallel to Sukhumvit Road, linking Asoke to Soi 23, needs little introduction.
"Siam Sam's" entrance is actually Cactus Bar, with the interior scenes filmed at Tilac Bar. We can't provide links to any of the sites that review these places for obvious reasons, but a Google search will easily lead the way.
The Scene: A clue leads the wolf pack to a party street and barber shop, where the boys find themselves strangely unpopular.
The Action: This was the set of "The Hangover Part II" that Bill Clinton visited, but the bars and tattoo parlor purpose-built for the film are not there anymore. (Contrary to rumors, the ex-president does not have a cameo role in this movie).
Small restaurants and bars line this pseudo-red light district, so you can have a drink and reflect on how "dead-end" applies to more than just the soi. To get there, take the BTS to Nana station.
The Scene: Crime figure Kingsley (Paul Giamatti) first appears.
The Action: The entrance to Bankgok's high-end Sirocco restaurant on the 64th floor of luxury hotel Lebua at State Tower provides arguably the most stunning views of Bangkok you can get, and was the site of several key scenes in the movie.
The hotel's Tower Club was also turned into a film set during the shoot, with the landmark "golden dome" on top of the building making a few appearances as well.
The Scene: Wedding for Stu (played by Helms) and fiancée Lauren (Jamie Chung).
The Action: The world's first Ritz-Carlton Reserve, Phulay Bay Krabi has 54 one-bedroom villas with private plunge pools, outdoor baths, 24-hour butler service and the limestone-studded splendor of the Krabi coastal landscape just a Champagne flute's throw away.
