IMDb has the I Need To Know board to answer these type of questions.
This is the place to post those film/TV/video/etc trivia questions you DON'T know the answers to - perhaps one of your fellow users can help.

From personal experience, there are a number of film buffs who delight in answering obscure or difficult to answer film questions such as the one you posted.
IMDb's get satisfaction site is primarily for reporting problems, asking questions about how to use IMDb and suggesting new features.
