- Billing Displacement: We have a two fold example. In the opening credits, George Newbern is given top billing as Superman before Jerry O'Connell and Zach Callison despite the latter two playing both sides of the protagonist Shazam. In the end credits, Josh Keaton and Danica McKellar are billed third and fourth, before George Newbern, Jerry O'Connell, and Arnold Vasolo, despite Josh and Danica playing minor characters.
- Children Voicing Children: Billy Batson is voiced by Zach Callison, who was 12 years when this came out.
- Playing Against Type: Josh Keaton, who usually plays good guys, voices the nameless thug who picks on Billy.
- Role Reprise: George Newbern returns as Superman and Jerry O'Connell returns as Captain Marvel. Fortunately, Black Adam gives them someone to fight besides each other.
