NEWTON (CBS) – If you drive along Commonwealth Ave. in Newton, the truck, trailers and extra security are giveaways something is going on. “It’s pretty cool to see the trucks lined up and to potentially see Cameron Diaz,” said neighbor Mary Dowdle. “We heard that she has a dog walker and she’s walking her dogs,” her daughter Margaux said.

Diaz and Jason Segel are in town shooting a new movie for Sony Pictures. According to the, Sex Tape is about a married couple that wakes up to realize the sex tape they made the night before is missing. “It’s cool. I mean Newton is pretty quiet for the most part, so anything everyone kind of takes notice. You can see everyone coming outside,” said Ashley Warren, who lives nearby.

The actual filming is taking place in a house in West Newton. “Big crowd here, but last night there was an even bigger crowd,” Andy Brody said standing across the street from the home. Tuesday night, he and his daughter’s saw Diaz briefly. We didn’t get a glimpse of the stars Wednesday, but were able to get very close to the set.

Neighbors who gathered along the usually quiet street said they were getting an education. “It’s very exciting to see movie production in our neighborhood,” Brody said. “I’m amazed the production cost, just how many people are here just to make a couple of scenes of a movie, just all the trucks and catering and all the people,” Brody explained.

Crews were also set up at Newton’s City Hall. Having a production in town, the mayor said, is good for the economy. “We’ve worked with production companies, you know, in the last several months. And from our standpoint, as long as the production companies are responsible and we work with our neighbors and we communicate properly and it doesn’t have an adverse impact, we welcome it,” Mayor Setti Warren said. After talking business, we tried to get some scoop, but the Mayor said he hadn’t met any of the stars. “I’m not clued into any of the secret Hollywood stuff,” he said.

Neighbors were told production will continue Thursday. Notebook in hand, 10-year old Samantha Brody knew what she’d do if she got close to the actors. “Can I have your autograph,” she planned to ask.
