When Bade Miyan Chote Miyan released in 1998, Amitabh Bachchan was in his mid-50s and Govinda was in his mid-30s. When this film came after 26 years coincidentally Akshay Kumar was in his mid-50s and Tiger Shroff was in his mid-30s.
Prithviraj and Akshay were part of Naam Shabana before but Akshay only had a cameo.
