Oh yeah, this is the trimmed version & not the original theatrical version.
Trimmed runtime : 2hrs 28mins
Original runtime : 2hrs 43mins
The silly train comedy is cut. For those unaware, Salman's Dhaakad is irritated by his aunt. So he decides to get rid of her while she's sleeping. He carries the whole katiya (bed) with her on it & sends her off on a midnight goods train. Only glitch, his mother Dimple Kapadia would've switched places & unknowingly he would've put his mother on the train. Long drawn painful comedy scene. But not worthy of being trimmed considering that is the only "so-called" family-wala scene among the flashback.
Also, Habibi Ki Nain is still part of the movie. Feel free to fast forward it.
