In order to immerse himself in the character's situation and mental state, Adrien Brody stayed in the woods overnight at the car wreck, completely alone, in the middle of a Canadian winter, while the rest of the cast and crew went back to their hotels.
During a Q&A at the Abu Dhabi Film Festival, the screenwriter (Dodd) revealed that he started writing the script as a "free-writing" experiment with no plan, no outline, and no idea of what was going to happen. On page one, when he realized that he didn't even know the identity of the main character, he put that idea into the script, too. The writer also said that the story, for him, was a metaphor for trying to get a movie made. "I would not, could not, give up," he said.
The teaser poster for Wrecked, which shows Adrien Brody's face behind broken glass was inspired by the poster for Straw Dogs. The writer and director created the poster themselves using Adobe Photoshop. The film's distributors liked the poster so much, they used it as is.
