MUMBAI: The Hangover Part II, director Todd Phillips’ follow-up to his 2009 box office phenomenon The Hangover, woke up number one at the UK box office this weekend with a staggering opening weekend of GBP 13,108 million (The 5 day opening weekend figure includes an estimate for Monday 30 May, 2011).

Warner Bros Entertainment UK president and managing director Josh Berger said, "Given the success of the first film, we knew it would have a huge audience, but these incredible results exceeded our expectations. Todd Phillips and his cast have delivered another comedy home run."

At the US box office, the movie took in $10.4 million, shattering the previous midnight-opening record for an R-rated film. The sum also more than doubled the record for a midnight opening of any 2011 film to date. With the widest opening of any R-rated film, The Hangover Part II went on to earn a total of $31.7 million on its opening day, setting a new opening day record for a comedy.

Warner Bros. Pictures president of domestic distribution Dan Fellman said, "From the tracking, we knew audiences couldn’t wait for another Hangover,’ but these numbers are through the roof. Leave it to Todd Phillips to create a new must-see comedy that has people lining up at the box office and rolling in the aisles. Congratulations to him, the cast and all the other talents behind the film on making another unforgettable comedy."

The Hangover (2009) earned $470 million worldwide, making it the top-grossing R-rated comedy of all time, and also won the Golden Globe for Best Film – Comedy or Musical.

Bradley Cooper, Ed Helms, Zach Galifianakis, and Justin Bartha star in the film, reprising their roles from The Hangover. The main cast also includes Ken Jeong and Jeffrey Tambor, who also return from the first film, and Mason Lee, Jamie Chung and Oscar nominee Paul Giamatti, who join the ensemble.
