May the laughter begin - "The Hangover" cast reunited on set in Los Angeles on Tuesday (September 11) to shoot the third installment of the comedy franchise.

All the usual suspects were there, including Bradley Cooper, Justin Bartha, Ed Helms and Zach Galifianakis, complete with plenty of facial hair, as usual.

The "Wolfpack" laughed and fooled around holding cups (containing non-alcoholic beverages, it is assumed) as they waited for hair and makeup.

The movie, slated for a May 2013 release, picks up from last year's "The Hangover Part II", which saw the boys run into all kinds of trouble in Thailand.
