Bozemanites brought their blankets, lawn chairs and picnic food.
"We brought some Swedish Fish and a bottle of wine" said Thompson Limanek.
"Lots of food, blankets, and chairs. And a dog" said Karen Arness.
They socialized and enjoyed the evening with hundreds of others in the community.
"It's nice to be out of the house on a summer day, and it's really nice out too" said a few kids on the Story Mansion lawn.
"We've already seen professors from the school, friends from around the neighborhoods" Limanek said.
It's for the 4th annual Story Under the Stars. Movie goers get to catch a classic flick in the great outdoors.
"We have a bit of a committee that every year brainstorms about what movies to do" said Andy Epple, president of Exergy Friends of the Story Mansion. "We try to have movies that are family friendly."
Exergy Friends of the Story Mansion and the Bozeman Film Festival host the event. This year's movie? "The Princess Bride."
The screen they're playing the move on is a 40-foot inflatable screen that's actually brand new to the event this year.
"The whole idea is about community building, and also to a certain extent, raise some awareness about the Story Mansion" Epple said.
Friends of the Story Mansion said they hope it'll let the community know what the mansion has to offer.
Many attendees like Limanek said it's an event "we've never been to before- hang out with the Bozeman community, beautiful night."
Limanek said they weren't planning on coming, and "it was just sort of a spur of the moment thing, but it sounded like it'd be a lot of fun to do."
Story Under the Stars is happening again next week, when they'll show "The Horse Whisperer," set right in Montana.
Epple said they'll have speakers that actually worked on the movie give a presentation before the showing.
