Here is the website that you can find most of my suggested movies above with English
Subs. It's free and easy to use. You shouldn't have to sign up or anything.
Well... the saddest I watched was Devdas. But the one where I really cried is Hum Dil De Chuke Sanam, but it has a happy ending, which is great. Both movies have Aishwarya Rai
Qayamat se Qayamat Tak
These aren't technically sad (some scenes are though) , but they're good: Tum Mere Ho, Aaina, Joddha Akbar, Beta, Devdas, Beenam Badsha, Vivah .....
Sorry, I felt like I just gave you a bunch of random list, but I really did enjoy them. Lol. Hope this helps!
