"Today is a very auspicious day. I am so glad that our dialogue promos and our anthem, 'Aala re aala' are out today. God bless our film," Gupta tweeted.
"Only three dialogue promos out yet, but I can feel the heat now. And the faint flutter of a butterfly in my gut," he further posted.
Inspired by Mumbai Police's first official encounter, "Shootout At Wadala" revolves around gangster Manya Surve, played by John Abraham.
It is scheduled for a May 1 release.
