Billing Displacement: Richard Sanders is featured in the opening credits and poster, but only has one scene as a Driver's Ed instructor. His character doesn't even get a name!
Covers Always Lie: The Valley Girl standing with Nicolas Cage's Randy in the movie poster is not actually Deborah Foreman's Julie. Word of God says that it is actress Tina Theberge, who plays Randy's ex-girlfriend, Samantha, in the movie. A budget DVD release of Valley Girl with The Sure Thing (as the Totally Awesome 80s Double Feature: The Sure Thing / Valley Girl) has Foreman's head obviously Photoshopped onto Theberge's body on the front cover.
Dawson Casting: Played very straight with Michael Bowen, who was 28 when he played Tommy. Averted with 18-year-old Nicolas Cage as Randy.
Billing Displacement: An unusual case of an actor being given a supporting credit despite not even having a speaking role. Peyton List receives a joint supporting credit with Jake Paul in the opening credits. This is despite her being effectively Demoted to Extra as List’s speaking role and musical number as Courtney, a cheerleader at the school attended by the main characters, were cut from the film, effectively limiting her to a background extra in several scenes. Paul, by comparison, appears fairly prominently in the film, making his crediting fit as well.
Played straight with Jessica Rothe who was 30 when playing high school senior Julie. Most of the other main cast members playing high school seniors were in the mid to late 20s at the time of filming, including Josh Whitehouse (Randy) and Ashleigh Murray (Loryn), Mae Whitman (Jack) and Chloe Bennet (Karen).
Oddly enough, inverted with Alicia Silverstone who plays adult Julie. Silverstone wasn't even 17 years old until 1993 but here she's playing a woman who was a high school teenager in the early '80s.
Deleted Scene: The soundtrack features a mashup of Toni Basil's "Hey Mickey" and Blondie's "Call Me" performed by Peyton List but the mashup doesn't appear in the film. Only a few seconds of "Hey Mickey" appear, as performed by a group of cheerleaders, but the full Peyton List version was cut.
The Shelf of Movie Languishment: The film was originally set for release on June 29, 2018, but then Logan Paul's controversies pulled it from schedule. It only came out in 2020, on drive-ins and video-on-demand due to the COVID-19 Pandemic.
