"That first seven minutes of the new Ram Gopal Varma film had me glued to the screen," tweeted Ghosh.
"The Attacks of 26/11" is based on the 2008 Mumbai terror attacks and its trailer was showcased Friday. Varma intends to release it in early next year both in Indian and international markets.
The trailer was screened just two days after Pakistani Ajmal Amir Kasab, the sole Pakistani terrorist who was caught alive in Mumbai, was hanged in a Pune jail.
Varma has made the film with new actors.
