Apparently after almost being shelved the film Time Machine which received a breath of fresh air has now been given to Aamir Khan to produce. The perfectionist Khan is all set to produce the film and will also be choosing the director for it. Since the film is somewhat a comic caper it is said that he is looking for a director who is adept with comedy. Besides this it is also rumoured that the cast will undergo a change and Naseeruddin Shah and Raveena Tandon are to be replaced, while another person will fill the void left by Amrish Puri. So we guess we will have to wait for the right time.
