Well, there are so many these days in every second movies, but in my opinion, Nargis and Rajkapoor in Awaara, Rekha in Utsav, Shashi kapoor and Zeenat in Satyam shivam sundaram, Rekha and Navin Nischhal in Aastha, Amol palekar and Smita Patil,Karishma and Amir in Raja Hindustaani, are few among the old classics of Indian Cinema and being hot and sensual, they are well performed and potrayed on the screen.Coz its not the nudity but the story and feel make the scenes hot in the movie.
I think mallika sherawat and Emraan Hasmi's sex scenes from the movie murder was the most sexiest and erotic one till date. Followed by the one from the movie oops, a scenes in the song jaane ye kya ho raha hai....
Yup to my point of view its not a problem but to readers it may be like abuse...so at that time Dayawaan it was tremendus and most of the people went to the movie for this scene after the entry of mallika and imran it became quite a passion..so no worries
