Anna's tattoo reads: "I have loved the stars too fondly to be fearful of the night."
Anna Camp designed the hummingbird tattoo behind her ear just for this movie. Anna Camp loved it so much that she got it for real.
In an interview with the SAG-AFTRA Foundation, Anna Camp explained that the film was originally called "Anna" after the main character. The fact that the character has the same name as her actress, Anna Camp, was just a coincidence.
