Aamir, 51, shared the trailer of the real-life inspired drama on social media, writing, "Here goes... Tell me what you think. Love. a."
The trailer begins with 51-year-old Aamir's character Mahavir Singh Phogat hoping that his yet-to-be-born child is a son, who will win a gold medal for the country someday.
However, when Mahavir is blessed with four daughters, he takes it upon himself to train them as world-class wrestlers.
He even tells his wife, played by actress Sakshi Tanwar, "Hamari <g data-gr-id="24">chhoriyaan</g> <g data-gr-id="25">chhoron</g> <g data-gr-id="26">se</g> <g data-gr-id="27">kam</g> <g data-gr-id="28">hain</g> <g data-gr-id="29">ke</g>?"
A heavily-bearded, heavily-accented Aamir is perfect in his restrained act of wrestler-father but it is his two daughters Geeta and Babita, played by Fatima Sana Shaikh and Sanya Malhotra, who shine in the trailer.
Produced by Aamir Khan, Kiran Rao and Disney's Siddharth Roy Kapur, "<g data-gr-id="21">Dangal</g>" has been <g data-gr-id="23">directed</g> Nitesh Tiwari. It will hit theatres on December 23.
