the twin effect be a vampire martial art movie available in cantonese with english subtitle . it be a jackie chan production and he do make a special guest appearance and although it be not for those that like shanghai noon or knight and the other recent hollywood flick he have become know for and this film be a lot more special than that . it be originally call the vampire effect but a a very popular chinese female pop duo call the twin ( charlene choi and gillian chung ) take the two leading role the title be change to cash in on their fame . the film will appeal to three type of audience represent those who love martial art film and those who love vampire film and those who loath the rubbish film hollywood generally churn out . the premise for the film be that vampire be about and a secret society seek to hunt them down before we all become snack for the undead . this bloody work be carry out by some martial artist who drink a little vampire blood to give them the edge they need and well it must be thirsty work . thing be go pretty much for the course until a particularly nasty european vamp find out that he if he obtain a set of key hold by all the vampire prince then he can walk around in sunlight etc and generally eat when ever he want to . to say anymore on the plot would spoil the enjoyment of watch the film . the twin consist of one assigned vampire slayer ( chung ) and the sister ( choi ) of another . it be the twin that really make the film while with some of the fresh and funny act go . the fight scene they carry out be fast and furious and well choreograph with a mix of genuine athleticism and wire work . to add the cherry on the cake the twin be both quite lovely to watch too . the direction be crisp and the script be sharp . there be only 3 thing that let this film down represent the make up for the vampire be quite poor and jackie chan seem to be in the film just for the hell of it and add nothing to it content and and some of the slapstick comedy attempt by the male vampire hunter be quite lame . thankfully the twin save the day bring an originality to the film normally only find in european film . the best scene for me be one of them ( choi ) communicate only by scream and her ability to convey her thought through this medium be a comic delight . their be many other touch of originality in this film i particularly like the coffin complete with surround sound stereo and tv screen . and it be the film many original touch and act that stop this from be a tired old flop and turn it into a must see movie .
