When it comes to early '90s action, few things are more iconic than "the Muscles from Brussels" doing a split. But in 1991, Jean-Claude Van Damme (JCVD) upped the ante by giving us two of them. Double Impact wasn't just another martial arts flick; it was a high-concept experiment that proved JCVD could carry a movie—and himself—in dual roles.

Raised in Los Angeles as a polite, pastel-wearing martial arts instructor.

The story follows twin brothers, Chad and Alex Wagner, who were separated as infants after their parents were murdered by a Hong Kong crime syndicate.

Made on a budget of roughly $15 million, Double Impact doubled its money at the box office, raking in over $30 million. It remains a staple of '90s action cinema, often cited by reviewers as the film where Van Damme truly solidified his status as a leading man capable of more than just throwing a punch.

A cigar-chomping, street-smart smuggler navigating the gritty underworld of Hong Kong.

The film features Bolo Yeung as the villainous Moon. After their legendary encounter in Bloodsport , seeing them face off again in a climactic battle was pure fan service.

Watching Van Damme fight his own stunt double (dressed as his twin) was a technical feat for its time. It allowed the star to showcase a bit more "acting range"—or at least two different haircuts.
