Be sure to reach out to the Alamo people as well, as they might be helpful in legitimizing your request to a studio who owns the rights.

Technically, all of those distributors at one time held the rights to distribute and store that material. No telling if the rights have lapsed or where the masters are being kept, if at all. Your best bet would be De Laurentiis, who according to IMDb handled the USA theatrical release. There is a good chance if Alamo screened it in SoCal there exists a print in one of the big studios’ storage, or perhaps DEG will have a copy.

I would start by finding a contact at De Laurentiis and asking them to provide you with information about the 35mm print masters.

In addition, Cynthia, being a close contact to him, may be helpful in connecting you with people related to this film.

try LinkedIn and message the Alamo distribution/ programming people with this request. In addition you could look up who owns the rights to this film and request a contact at that company. There are entire departments that handle these requests… although, no guarantee if that 35 print is findable or exists where they say it does. good luck
