UPDATED: The R-rated comedy starring Bradley Cooper is enjoying one of the best Thursday openings of all time, while "Kung Fu Panda 2" grossed roughly $6 million in a solid start for the 3D toon.

Warner Bros.' The Hangover Part II is living up to its hype at the domestic box office.

The R-rated sequel is on track to gross north of $30 million on its first day, one of the highest Thursday grosses of all time.

Paramount and DreamWorks Animation's Kung Fu Panda 2 also opened Thursday in advance of the long Memorial Day weekend, grossing roughly $6 million in a solid start for the 3D toon.

Hangover's tally includes $10.4 million in midnight runs from 2,600 theaters, an all-time high for an R-rated film.

On Thursday morning, Hangover moved into a total of 3,615 locations, the widest opening ever for an R-rated title.

Box office observers believe Hangover will gross between $110 million to $125 million between now and Monday, though Warners is being more cautious and estimating a five-day opening closer to $100 million.

Set in Thailand this time, Hangover Part II returns Bradley Cooper, Ed Helms, Zach Galifianakis, Ken Jeong and Justin Bartha in the lead roles. The film isn't drawing great reviews, but it's without a doubt the most anticipated title of 2011 so far.

Among films opening on a Thursday, only four movies in history have posted an opening day gross of $25 million or more: Star Wars: Episode III -- Revenge of the Sith ($50 million, 5/19/05), The Matrix Reloaded ($37.5 million, 5/15/03), Star Wars: Episode II -- Attack of the Clones ($30.1 million, 5/16/02) and, most recently, Indiana Jones and the Kingdom of the Crystal Skull ($25 million, 5/22/08).

Hangover was co-financed by Warner Bros. and partner Legendary Pictures.
