Before Russell Crowe was cast, Mel Gibson and Nicolas Cage were originally considered for the lead role.
Russell Crowe allegedly demanded that the step on his trailer be dismantled and replaced with a custom step for the brief periods he would spend in it during filming. The crew found him extremely difficult to work with.
The movie is inspired from a south Indian movie named 'Mumbai Police'
Russell Crowe and Karen Gillan both appeared in Thor: Tình Yêu Và Sấm Sét (2022) as Zeus and Nebula, although they did not share any scenes.
