The film is an official remake of the 2011 Hollywood film "Warrior".
"The last of the love & hugs of #Brothers. My final shot of a film that my body & soul will never forget! Many thanks," Akshay, 47, posted on Twitter.
"Brothers", also starring Jackie Shroff and Jacqueline Fernandez, is a story about two estranged brothers.
The first look poster of the film was released last month. "Brothers" will hit theatres on August 14 this year.
