You don't often get almost 200 movie stars in the same room in Hollywood, let alone Wareham.  But while the red carpet and throngs of paparazzi were absent, the star wattage was high as young actors and their entourages - or rather employees at Water Wizz and their friends -  attended a special premiere showing of Grown Ups on Thursday at Flagship Cinema.

The movie, which filmed at Water Wizz for six days last August, follows five childhood friends, played by Adam Sandler, Chris Rock, Kevin James, Rob Schneider, and David Spade, who reunite after their beloved basketball coach's funeral to spend the Fourth of July weekend at the coach's lake house with their families.

Of course, hilarity ensues as the divergent paths of life that have led Sandler to become a successful Hollywood agent with a mansion and Salma Hayek as a wife (see, told you it was funny...), share a home with masseuse Rob Schneider and his elderly girlfriend, henpecked house-husband Chris Rock, and other cliched characters and their surprisingly normal children.

But, surprise, they all bond, and they decide to cement their new friendship by visiting Water Wizz.

And that's what the audience wanted to see.

As the movie's 20-minute long "montage" scene, the park and its attractions feature prominently.   And while searching for their faces onscreen, the audience hollered as the familiar setting provided lots of comedic fodder - wedgies from the Pirate's Plunge, soakings from the frog bucket, and trying to cut the line at Hurricane Hill by following a secret passageway through a shed (it doesn't exist, staff noted, they constructed the shed for the movie).

The audience loved it, cheering and laughing throughout.  Even the movie's predictability - made even more predictable when you know what really happens if somebody, for instance, pees in the pool - didn't stifle the laughter.  The audience cheered even more loudly when the stars show up for the movie's climactic basketball game wearing Water Wizz t-shirts.

"It looked so good," said Megan Kingston, who is working at Water Wizz for the second year this summer.  "It was so cool to see it onscreen."

"I loved it, it was so funny." said Kaitlyn Chuba, who has also worked at the park for two years and said that she was most excited to see Adam Sandler at the park during filming.   She and other workers even got to meet and talk with the actor.

Water Wizz Operations Manager Jackie Williams, who organized the event with Flagship, said that it was great to see the exposure that Water Wizz received, but that it had been hard work for those six days last summer.

"They were long days," she said.  "But the kids got to eat in the catering tent with the actors and crew, which was real cool." She also said that the movie crew was very organized, knew what they wanted and then just took control.

And while the movie hasn't exactly wowed the critics as being either particularly profound or funny, it has its moments.  Plus, how often do you get to see Wareham star on the silver screen?
