Jean-Claude Van Damme had numerous reasons for writing, producing and acting in Double Impact (1991). One of the reasons was to show his ability to play conflicting roles and thus to help change his image. Jean-Claude Van Damme said about the twins, “One of them is violent and the other is not, so the audience can see the contrast in my work.” “This picture has comedy, romance, a love story. So it is not all action and fighting. When I fight on screen, I blend dancing and fighting. Grace plus power is very nice.”
