When I was a high-schooler, there was this film Pyar To Hona Hi Tha. How I liked that one! I bunked classes twice to go watch that movie. Later, I came across the movie French Kiss, and was so disappointed that one of my favourite movies was a rip-off!
Deja vu, repeats all over again! I just found that Life In A Metro took the lending-out-the-apartment-to-superiors idea from The Apartment. Saving grace, that idea remains one of the various sub-plots in the movie and the meat of the story takes a different angle, who knows copied from where.
