The film is about four teens who get pulled into a video game and have to pick their avatars. So we made the audience do the same. A "Choose your player" screen, styled like the game in the film, asked the theatre to vote on their phones for Spencer, Martha, Bethany or Fridge. The winning teen's trailer then played on the big screen, revealing who they become in the game: Dwayne Johnson, Karen Gillan, Jack Black or Kevin Hart.
