Hi Bob,
The wedding footage can probably be converted to a digital format so you can relive the day.
Here's a couple from a quick search:

As for the photos.....
Do you know when/where they were taken? If it's from "events" then maybe the organisers would like them. Some have an archivist who would doubtless love them.
Maybe for the cars there's owner's clubs that might be interested?
Enjoy the memories as you go through.
