Actor Arjun Rampal was nervous when he took his wife Mehr to watch a preview of his forthcoming film "D-Day" because she is his "hugest" critic.

"D-Day" releases July 19.

"Going to watch 'D-Day' with my hugest critic ... my wife! The most nerve-wracking feeling before release. Wish me luck (that) she likes it," Arjun tweeted Wednesday.

Arjun and Mehr married in 1998, and together they raise two daughters - Mahikaa and Myra.

In "D-Day", a crime thriller, Arjun essays the character of Rudra Pratap Singh, an ex-officer of the Indian armed forces MARCOS unit. Co-produced by DAR Motion Pictures and Emmay Entertainment Pvt. Ltd., the movie also stars Rishi Kapoor, Irrfan, Shruti Haasan, Huma Qureshi, Akash Dahiya, Sree Swara and Chandan Roy Sanyal.
