For some actors in the film who never got to wear a prom gown or tuxedo, this pretend-world prom counts as their own chance to attend the big dance.
Other actors did go to their own proms, but now know they didn't appreciate the night the way they should have.
"I kind of sort of regret not making it a bigger deal," said actress Aimee Teegarden. "I think I was kind of too cool school for school back in the day. I went and it was fun, but I regret not going all out."
"Prom" weaves together stories of various high school students as their lives intersect on the big night.
Along with the ensemble cast, another major player will be recognizable to the L.A. crowd: Burroughs Middle School.
The Mid-Wilshire neighborhood school serves as the alter ego for the high school in the movie.
"Prom" is rated PG and is in theaters Friday.
