New Delhi: Actors Vivek Oberoi, Aftab Shivadasani, Riteish Deshmukh and Urvashi Rautela chose to stay mum on the online leak of their forthcoming film "Great Grand Masti" prior to its release. The movie, a "naughty comedy", got leaked online and High Definition (HD) prints were available for download. Asked to comment on the leak, Vivek told reporters here: "Unfortunately, we cannot talk on this topic... our film's production house will issue on a statement on this." Following the online leak last week, the movie's makers rescheduled its release date, putting it out a week before it was slated to hit the screens. Directed by Indra Kumar, "Great Grand Masti" is the third part of the "Masti" franchise. It will hit screens on Friday.
