Doing something similar myself, thoroughly enjoying revisiting those decades, music and TV series too. Bit of a random mixture off the top of my head -
Dirty Dancing, Sleepless in Seattle, Working Girl, Jerry Maguire, When Harry met Sally, Moonstruck, When a Man Loves a Woman, Ghost, How to Make an American Quilt, Little Women, Stand by Me, Back to the Future, Tootsie, Beetlejuice, Four Weddings and a Funeral, Room with a View, Howards End, Notting Hill, Clueless, Shakespeare in Love, Desperately Seeking Susan, An Ideal Husband.
Not made, but set in the eighties so a big hit of nostalgia - The Wedding Singer, Thirteen going on Thirty.
