For filming, Rachel's red Acura was transported from Littleton, Colorado to Nashville, Tennessee.
The initial release date was April 20th, 2016, the 17th anniversary of Rachel Scott's death. It was moved to October 21st, 2016 at her parents' request. The movie is meant to be a celebration of her life, not her death.
When Rachel pulls into the school parking lot, she passes a sign that says "Good Luck Band"; this was the message on the school's sign the day of April 20, 1999.
Executive producer Benny Proffitt arrived at Columbine High School hours after the mass shooting for a scheduled school program. At the time, he was leading a Tour Across America to every state, with 40 college students.
The character of Sean is based on Brooks Brown. The scene where he and Rachel discuss religion at the Smoker's Pit is based on a recollection from his book, "No Easy Answers". Though he was an irreligious, Brown came to admire Scott.
