Pritesh,
More information would be helpful to us. Are you shooting color or B&W? I just watched a british film called The Mother shot in color Super16 and it did a great job of conveying a feeling of alienation. On the other hand, the film Eraserhead, which was shot in 35 B&W, was key to the development of the visual sensibilities of The Shining. Choosing a stock depends heavily on your projected visual style for the film.
