Aamir is playing an antagonist for the first time in Dhoom 3, the third instalment of the Dhoom franchise that started in 2004. In the first two films, John Abraham and Hrithik Roshan played villains, respectively.
Talking about Dhoom 3, Rao said she knows "nothing" about the film other than "a little bit about the character that Aamir is playing, so I am excited because this is the first time in seven-eight years I don't know anything about a film that Aamir is doing."
She was talking at a press conference of Anand Gandhi's film The Ship of Theseus, which she is releasing in association with UTV Motion Pictures.
"I have always been one of the few people to hear the narrations (of Aamir's films) very early and I was like, 'at least for once let me come in as an audience and watch your film'. I want to go there, not knowing anything, be able to react as an audience, so Dhoom 3 is that film," Rao told reporters.
Aamir is paired with Katrina Kaif in Dhoom 3 that is directed by Vijay Acharya, while P.K. is Raj Kumar Hirani's directorial venture, in which Aamir will be seen sharing screen space with Anushka Sharma.
The release dates of both the films are not yet confirmed.
