raja, sorry to say this but i think you are also a bit apprehensive about this fact. in my opinion and i think i am correct the bengali film "EK mutho chobi" ( a fist of images) by rupa ganguly which had a mainstream release 6 months back is the first portmanteau film. anyway nice work! i follow your reviews and interviews and really like them a lot. it has got substance. only saibal chatterjee is better than you. otherwise you are almost there!!
