1960s Hollywood movie so good at this genre, from Breakfast at Tiffany's to some of Elvis Presley movie with musical theme. Probably their scripts and environment in the 1960s is just naturally romantic compared to 1970s onwards way of making this type of genre.
1960s is Hollywood Romantic genre golden age, classy romantic with classic musical thing. Been a hobby digging and try to watch old Hollywood movie nowadays.
