AUBURN – Corey loves Amanda.

Amanda loves horror movies.

The solution was so simple, it was almost scary.

On Friday the 13th, at the movie of the same name, Amanda Pride was trembling. Her hands were shaking and she pulled a sweater over her face to cover her eyes.

But the shock had nothing to do with campers being menaced by a masked killer on the screen at Flagship Cinemas on Friday night. The Sabattus woman was in such a state because her boyfriend had just proposed to her in a cinematic way: The proposal played out on the big screen while the couple sat together several rows back.

“I’m shaking,” the 20-year-old Amanda said, over the applause of roughly 180 people who turned out for the movie. “I wasn’t expecting that. He’s really shy.”

The shy romantic is Corey Seguin, 18, of Lewiston. As soon as the on-screen version of himself popped the question, he did likewise in the real world. He jumped out of his theater seat and dropped to one knee. Gigantic Corey asked the big question on the mammoth screen. Life-size Corey did the same thing.

“She said yes!” one nearby movie fan hollered out when Amanda answered the proposal. The applause was immediate.

“Nervous,” Corey said when it was over. “I was nervous.”

Too nervous for either of them to stick around and actually watch the movie. They left the theater before “Friday the 13th” began, planning to go back later after discussions about wedding dates and other less horrifying business.

He got the idea from Amanda’s mother, who challenged Corey to go big with his proposal.

As it turns out, planning a theatrical wedding plea is no easy business. To get it done, Corey turned to Francis Gagnon of VIA-VISION Film & Video Productions in Lewiston. Not only is Gagnon a production expert, he used to manage Flagship.

He knew how to go about it. Sort of.

“I do wedding videos all the time,” Gagnon said before the movie. “This will be my first proposal.”

The first step was filming Corey, down on one knee, asking the big question. That was easy enough. To make the video more theater friendly, Gagnon touched it up with simple greetings, photos of popcorn and fountain drinks, simple Valentine’s greetings from Flagship.

Amanda said she did not know something personal was being played out on the screen until her boyfriend appeared there.

“I thought, wait. This doesn’t have anything to do with ‘Friday the 13th,'” she said.

It sort of does, though. Corey decided to combine that grim date with Valentine’s Day to create a proposal custom-made for the couple. Nobody can argue that it’s not unique.

“As far as I know, it’s a first,” said theater manager Nancy Holt, who helped coordinate the theatrical release. “It’s never been done at one of our theaters. I’m excited. It’s a fun way to do it.”

There was no immediate word on when the couple would wed, or whether “Friday the 13th” character Jason Vorhees would be invited to the ceremony.
