After Aamir saw the trailer of Shahid, which is based on the life of slain lawyer and human rights activist Shahid Azmi, he decided to support the movie. The actor also posted the trailer on his official Facebook page.
"I am thankful to him (Aamir)... It feels good that he is promoting the film. It is a warm gesture," Mehta said.
"There was no reason for him to do so but he went ahead and spoke well about the film. He supporting the film is a big thing," Mehta said.
Recently, filmmaker Karan Johar played an active role in the promotion of Irrfan Khan starrer The Lunchbox as a presenter, while director Kiran Rao presented Ship of Thesus.
Both films, falling in 'parallel' bracket, were benefited by the support, and did well at the box office.
However, Mehta clarified that Aamir was not "presenting" the film.
Releasing on October 18, the film, starring Rajkumar of Kai Po Che! fame, is distributed by UTV Motion Pictures.
