Returning to its barnstorming, no frills antics is The Hangover franchise, which enters its third film, due for release this summer in the U.S.A. “This time, there's no wedding. No bachelor party. What could go wrong, right? But when the Wolfpack hits the road, all bets are off,” reads the synopsis. Watch the trailer now.

In a recent interview with Digital Spy, screenwriter Craig Mazin promised that unlike "The Hangover Part II," the final adventure wouldn't just be a replay of the first. "It's going to be quite a bit different," Mazin said. "The storyline is quite a bit different, but it's still the four guys that are on an insane adventure. Frankly, Todd and I really approached this in the point of view of a great ending to a trilogy and it kind of explains quite a bit and ties back to the first movie in a very interesting way. I think Todd did an incredible job."

The initial Hangover movie did well, scoring 79% on review aggregator site Rotten Tomatoes, but the second film plummeted down to 34% and was considered a disappointment. Still, both films performed well financially, and with its strong reputation, part 3 should be topping box office charts come Monday 27th May. The Hangover III is out on the 24th in both the U.S and the U.K.
