 After receiving the unusual writing credits (Story by  Jeffrey Boam (qv), Screenplay by Jeffrey Boam and Jeffrey Boam &  Robert Mark Kamen (qv)), 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. A few still  remain in circulation, however.
