At some point or the other, we all wish if we could have a time machine or a special gadget that takes us into the future. While ours may only remain a wishful desire, our B-town actors and actresses certainly seem to be having a blast on-screen either delving into the past or taking a ride into the future. Helping them in this cause are the numerous gadgets from wrist watches to cameras to time-machines. This weeks release Aa Dekhen Zara has Neil Nitin Mukesh playing a photographer who gets hold of a rare, special camera which helps him to see the future. The camera becomes a constant companion to Neil (besides Bipasha) in his journey in the film. In this exclusive slideshow, Bollywood Hungama takes a trip down memory lane and a ride into the future to recollect some recent films where our actors have the unique privilege to re-visit the past or see the future.
