"As people, there are a lot of similarities between Aamir and Salman. Both are extremely warm, very friendly and down to earth. Not at all pretentious, " Asin told over telephone from Mumbai.
"As actors their working styles are quite different. Like for example when Aamir used to come on the sets to shoot, he used to sit with the cast and crew and used to discuss the scene, give his ideas and his inputs; he used to be quite involved, " the 23-year-old said.
"On the other hand, Salman used to come on the sets, shoot for the scene and leave. There used to be no give and take of ideas; so it used to seem very spontaneous. However, I am sure in his mind he must be knowing exactly what he has to do and how he has to do it, " she added.
The actress, who was brought up in Kerala and debuted in Sathyan Anthikad's Malayalam film "Narendran Makan Jayakanthan Vaka" in 2001, created a mark in the Hindi film industry with "Ghajini" in 2008.
She is ready with her second Bollywood venture "London Dreams" that stars Ajay Devgan along with Salman.
Asked if she was nervous being in the same frame as two such experienced actors, Asin said she neither felt nervous nor intimidated.
"When I go on the sets, I forget all my inhibitions. When I was working with Ajay and Salman, I didn't feel any pressure, maybe because they themselves did not behave like stars and threw no starry tantrums.
"When you work with such dedicated actors, you also do your job well and try to learn whatever you can. But there was no intimidation... I was not scared or anything to work with them. They are experienced but also make you feel very comfortable, " Asin said.
"London Dreams", slated to release Oct 30, tells the story of two childhood friends who dream about making it big in the music industry and start a band. Asin, who is a dancer in the band, is the love interest of both friends.
So what made her sign the film?
"When the film was offered to me, I was keen to do it because I had worked with a star like Aamir in my first Hindi venture and in this one, there were two stars; so that was a 'double dhamaka'.
"Apart from that I loved my character Priya, which is quite different from my earlier role, and also a filmmaker like Vipul Shah is making the film. All these factors made me say yes, " Asin said.
