<span class=normal>For executing the background replacement shots, we took many photographs of the Bandra Worli sea link, and shot the background plates of it from all the requisite angles. Using matte paintings, we recreated all the backgrounds differently as per the shots. We did some night shots which were a little difficult, as we had to blend the background to the foreground and make it seem natural. One of the most challenging parts with the VFX for this film was that, we had to coordinate with doctors throughout and seek their approvals for taking the specifications of the heartbeats, pulse rates etc. which we changed according to the actors expression and narrative requirements. This was a regular exercise so we made every single hospital monitor shot look perfect and credible in the film. </span><br><br><amp-img width=1.33 height=1 layout=responsive src=https://images.bollywoodhungama.com/img/feature/13/jul/also4a.jpg></amp-img>
