Innocence (2000)

Synopsis
Lovers in Belgium during WWII, Claire (Julia Blake) and Andreas (Charles Tingwell) are shocked to discover that, after a 45-year separation, they are neighbors in the same Melbourne neighborhood. Andreas has been a widower for 30 years, while Claire is happily though not passionately married to John (Terry Norris), whom she hasn't slept with for two decades. Andreas and Claire resume their heady sexual relationship, much to the disapproval of their loved ones. Director Paul Cox cuts between footage of the couple in the present and the past, examining how they have and haven't changed over the years, and the bond that continues to keep them together. ~ Rebecca Flint, All Movie Guide
