The 37-year-old "Hamari Adhuri Kahani" star, who also stars in the film, shared the poster of Captain Nawab on Twitter with his fans.
"And here it is, my first home production movie!!," he captioned the poster.
The actor is looking intense in the army uniform with guns in his hand and a background of Indian and Pakistani flags.
This is Emraan's second film with director Tony D'Souza.
The two earlier teamed up for Azhar.
The film which has a tagline- "Two Countries. One Soldier," seems to be a cross-border story, written by Nitin Upadhyaya.
