How would you implement this?

I was wondering what people might think is the best way to implement this kind of functionality?

I am creating a movie production services directory that includes, locations, cast and crew. I would like to have a user create a project that includes a list of Actors (characters) and locations needed for a specific script.

On its simplest terms having a new “fantasy” place defined (lets say “old Victorian Mansion”) for each needed location that would then use the “Related Listing Function” is one theory that might work. Linking the results in some list together would let the user have define selects and eventually define a final option.

Same for a Talent / Actors directory used to suggest actors for a specific role.

Anyway, any ideas on implementation? What might be the overall scheme –
“special” category of posts within a specific post type that are used to create a link / relationship?

Or would some sort of saved “advanced search” that was defined by filling out a form and then saved under the “ideal Location Name”

Any ideas?

Hoping the GD listing becomes available for other themes soon
