Bradley Cooper, who grew up in Jenkintown, is in Upper Darby shooting "The Silver Linings Playbook."
Action News was on the set for the scene where Cooper's character returns home after a stay in a mental hospital.
The fans are just crazy about him. They brought their cameras and their kids.
"When my girlfriend told me he was over here, we had to go see them. It's [my kids] first lesson in star stalking," Cherie Bradley of Drexel Hill said with a laugh.
The movie also stars Robert DeNiro and Jennifer Lawrence, who were not at the taping.
The film is directed by David O. Russell who's last movie "The Fighter" won two Academy Awards.
He's known for authenticity, and that's why they're here in Upper Darby.
"It's not easy because you want what you're after, why we want to shoot in these neighborhoods, is because we want to have the authenticity and really have the feel of where the movie takes place, but you really need the cooperation of the neighborhood and the people that are there," Russell said.
The people who live on this block agreed to stay away during the shoot, but they say it's no great inconvenience.
"I think it's exciting, I think it's great. So I got to walk a block. I think it would do me good to walk some of these pounds off," Upper Darby resident John Cawley said.
This production could be coming soon to a neighborhood near you. They'll be hopscotching around the Delaware Valley for another 30 days.
