Althought her 'Queen and Tanu weds Manu return were super hit on box office but recently her 'katti Batti' was a flop on the box office.Well for now she is busy with upcoming Vishal Bhardwaj's 'Rangoon'. Because of this,one of her film 'Simran' got postponed which Hansal Mehta wanted to make.Yes,shooting of the film was about to start in America next year in March but now it has been postponed because Kangana loves doing only one film at a time. Right now she is totally focused to 'Rangoon',which is expected to finish in February, but as we know Kangana she works on post production after shooting is done,that's why she cannot work in any other film and when she has to shoot in Abroad.
