Your movie was shot on film and you don't have master film or audio materials.
Do you know which lab(s) was used for the film?*
Yes - and the lab still exists -contact the lab
Yes - but the lab is out of business:
Contact Missing Movies for assistance
No - but I have a film print of the finished version:
Check the print for lab markings
Check the End Credits to see if a lab is credited

*Note: The lab where you dailies were processed is likely to be different from where the release prints were made and where the distribution elements for the final version were stored. The original processing lab may have the original camera negative but you are looking for distribution elements - Interpositives, Internegatives, Audio Mag Tracks, etc.
