Filmed as an answer to Jean-Claude Van Damme's Double Impact, the 1992 Jackie Chan film Twin Dragons, redubbed and re-edited for American release, gets by on the novelty value of having Chan play a dual role. Co-directed by two of Hong Kong's most notable filmmakers, Tsui Hark and Ringo Lam, Twin Dragons ought to have been a tour de force. Instead, it's a bit sluggish by Chan's standards. Chan plays two brothers separated at birth, one a classical musician, the other a kung-fu-fighting race-car driver. When the two show up at the same posh hotel, much confusion ensues, generally symbolized by the twins' tendency to instantly provoke fainting in those who see them together. As an examination of the slipperiness of identity, its relation to physical appearance, and the incomprehensible knot of coincidences that binds the world together, Twin Dragons won't make anyone forget Comedy Of Errors, Dead Ringers, or The Double Life Of Veronique. Missing at least two remarkable action set-pieces, it probably won't make anyone forget Dragons Forever, Wheels On Meals, Project A, or any number of other excellent Chan films, either. But Twin Dragons is still a Chan film, albeit not a great one. As fans have figured out by now, that goes a long way.
