Sooraj and Athiya made their Bollywood debut together in 2015 with superstar Salman Khan's production "Hero".
The romantic action film is directed by Nikkhil Advani and is a remake of veteran filmmaker Subhash Ghai-directed 1983 film of the same name.
Athiya will soon be seen sharing screen space with actors Anil Kapoor, Arjun Kapoor and Ileana D'Cruz in "Mubarakan", directed by Anees Bazmee.
