New Delhi, Oct 6 (IANS): Director Indra Kumar's adult comedy has hit the bull's eye at the domestic box office - it has crossed Rs.100 crore mark and a trade analyst says it has become "the first adult film to attain the status".

"And it's a century... 'Grand Masti' crosses Rs.100 crore net mark in India. First 'Adults' film to attain this status," tweeted trade analyst Taran Adarsh.

Aftab Shivadasani, who plays one of the male leads in the movie, took to the microblogging site to share his excitement about the film's growing numbers at the ticket window.

Aftab, seen as Prem in "Grand Masti", tweeted: "And history is made - the first adult film to make Rs.100 crores! Feeling elated to be a part of history! Thank you all."

Also starring Riteish Deshmukh and Vivek Oberoi as the male leads, the sequel to 2004 hit movie "Masti", came out Sep 13 as it was panned by the critics for being too vulgar.

Co-produced by Ashok Thakeria and Indra Kumar, the film has been presented by Bharat Shah and distributed by Eros International Worldwide.

After minting Rs.66.4 crore in the opening week, the movie has entered the prestigious Rs.100 crore club in its third week.

Shah is happy about the Indian collection and told IANS: "It's very good".

Asked if this indicates that the audience has started accepting sex comedies, he said: "Yes, definitely. The credit goes to the director and producers of the movie and also to the cast."
