Screenwriter Jeffrey Boam is credited twice in the 'screenplay by' credits. This is because he did one draft by himself (granting him the first credit) and a second draft collaborating with Robert Mark Kamen (granting him the second credit). In this rare scenario, Boam was hired to rewrite his own script with a second writer. After receiving the unusual writing credits, the advertising department assumed it was a misprint and produced posters with the credits "Story by Jeffrey Boam, Screenplay by Jeffrey Boam and Robert Mark Kamen". After a few of the posters had been sent out, the WGA contacted the department, telling them that the initial credits were the correct ones, and ordering the posters to be recalled and destroyed.
