A good but difficult Q to answer. Romance as a subject has been one of the most popular subjects. And there are too many movies to recollect.. but recollect I must, because things change with Age & Experience!!! (ahemmm).
Raja Harishchander: Badhiya romance tha, shayad. As a child didn't know a thing as to what is was anyway.
Haqiqat: Dharmender & Priya Rajvansh. Remember the song when the 'Fauji's' get a letter from home and remember their wives. What romance...
Lalkaar: Dharmender & aaree ke naam tha us choori ka jo Kabile ki raani ban rhi thee.
Guru Dutt Movies always depicted romance with a new angle..
Julie: Bhai, U naya romance dekhyaa...
Bobby: Haan bhai haan, Sheila Theater, Rohtak. Ar kai be..
Sholay: Ditto to what Shail said.
Ghatak: The song that Sunny Deol and Meenakshi Sheshadri sing.."Nigahon mein...".
Romance ka Baap: DHARMENDER tells Dimple in a movie (Batwara it was, shayad), "Tu mere kanne aa jya, Tere Phal bhi laag gein ge ar Fruit bhi". A must watch for all romantics..
Aaj kal ke romance? Bhaandgiri hai...
