The box office clash between Sunny Deol's Gadar 2 and Akshay Kumar's OMG 2 has kept trade analysts on their toes. The euphoria among fans is unmatched and the result is evident. While people are flocking to cinema halls to watch the film of their choice, theatres are once again experiencing the best phase. Amid the clash, the audience who watched OMG 2 in cinema halls, must have noticed an interesting connection with regard to Sunny's Gadar (2001).

In a key scene from OMG 2, Akshay was seen singing the song Ud Ja Kale Kawa from Gadar while lying under a tree at night. He plays the role of Lord Shiva's messenger. A Shivgan, he ascends on Earth to support Mahadev's devotee Kanti Sharan Mudgal (Pankaj Tripathi) in his case against his son's school for not prioritising sex education. The reprised version of Ud Ja Kale Kawa is a part of Gadar 2.
