"It automatically speaks something about the content of the film. He is someone who is known to attach himself to a film that has a serious story to tell and something new to share with people, " the 38-year-old said here Monday at the success party of the film.
"He is known to do that and when he attaches himself to a movie like Talaash, it automatically sends out a signal to the people that there must be something interesting going on in the movie, " he added.
Besides playing the lead as Inspector Surjan Singh Shekhawat, Aamir was also the co-producer of Talaash along with Farhan and Ritesh Sidhwani.
Farhan, however, accepts that Aamir's celebrity status is also a major reason why people come to watch a film.
"This is completely apart from his celebrity status. That of course brings in numbers and it brings a lot of people wanting to watch him as fans, but also, I think it brings in a certain credibility to a project, " Farhan said.
Farhan also wrote some dialogues in the film, while his sister Zoya co-wrote the story along with film's director, Reema Kagti.
