Happy Madison Productions and Sony Pictures Entertainment are set to begin filming “Grown Ups 2” starting mid-May, 2012 in Massachusetts. The casting directors are holding two open casting calls seeking a very large number of kids, teens, and adults of all ages and types to work as extras in the movie. Anyone in Boston, New Hampshire or Rhode Island can attend. Shooting will continue through August 9, 2012. No prior experience is required, and both union and non-union extras are welcome.
