The most delightful thing to me about this light comedy is the "invention" of playback singing as a seduction strategy for Sunil Dutt. His Guru in the movie is a director of what appears to be neighborhood Mahabharat dramas, with pan juice usually dripping toward his chin, played by Kishore Kumar.
Sunil wants to be able to sing to impress the sexy neighbor girl -- but he can't -- so Kishore comes up with the brilliant idea that HE will sing out of sight, and Sunil will -- well, picturise the singing! Fantastic idea!! Which generates wonderful scenes of Sunil picturising seductively while we also see Kishore hopping around behind him singing the songs. (I imagine Kishore is actually playbacking himself here, so it's a great Bollywood-y hall of musical mirrors.)
Kishore also sings and dances a number in which I believe he is doing a ladies' dance, playing the part of the beloved, as part of the enterprise of coaching Sunil in his love quest. His comic talent and body language are spectacular. I''ll probably buy this one just to watch this scene 1000 times. ~Virginia in New York
