"Fireworks will explode as they unite for an on-screen fiesta that will welcome audiences of all ages and backgrounds to join in the fun and frolics, sure to leave a smile on the face, warm the heart and uplift the spirit," said a statement.
"Sun, sangria, siestas and senoritas will hypnotise cinema-goers with the feel-good film of the year."

Roshan is said to have worked 13-hour days shooting on the film, which is released on July 15.
