I've used films up to 20 years old with negligible loss of quality. Recently shot an Orwo color neg film, the last batch of C-41 dated 1992 before the factory closed, and the prints are indistinguisable from in-date Kodak taken at the same time.
The film was refridgerated most of the time, but had then been in bottom of one of my camera bags for at least a couple of years.

(But, obviously, don't use anything other than fresh film for your daughter's wedding....the possible consequences don't bear thinking about! )
