Dunno Y… na Jaane Kyon deals with the subject of homosexual love. The movie stars yesteryears greats Helen ( as a great grand mom), Zeenat Aman (as grand mom) , Kabir Bedi and Kolkata based actress Rituparna Sengupta and Karan Sharma. Anyhow the film is about a Christian family. Everyone is having fun on the sly. Rituparna who plays mom has fun with her brother in law and even the grandmom has her own flings. The movie is notorious for its moaning homo love scene in a hotel in Goa. There is plenty of bad English in the movie, evidently the script writer has never heard of proper English grammar. All in all a below average movie.... should disappear in a flash.
