Casts:

Reeve The Vampire Slayer (Ekin Cheng)
Aloof and reserved with dashing (not) hair to boot, Reeve is one of the top vampire hunters in the Anti-Vampire League. The League provides its employees with vampire blood to give them temporary power. The vampire blood must be "released" from the hunters' bodies in the form of an antidote disguised by banana essence, otherwise the hunters become real vampires themselves. Anyway, Reeve is after his 124th kill in the form of Duke Dekontes (played by Mickey Hardt; more on him later), one of the most powerful vampires in Vampireland (or wherever these bloodsuckers are from -- it's not made clear in the movie). After losing his partner-lover Lila (played by Josie Ho) in a battle against Duke Dekontes, Reeve vows to never fall in love with his partner again...

Helen The Fake Juliet (Charlene Choi)
Reeve's younger sister who has inherited some of his kung-fu skills but does not belong to the League. When we first meet her she's forcing her boyfriend (played by Chapman To, appearing in his 700th Hong Kong film of the year) to cut off a part of his body per his promise because he has apparently cheated on her (probably because of her non-existent fashion sense). A fingernail removal later, Helen is comforted by vampire royalty Kazaf, who immediately takes a shine to her spunky disposition. The two begin an odd courtship, superimposed by the fact that Kazaf can't stay in the sun for long, sleeps in a dope coffin (complete with plasma TV and neon lights whose lid opens when it hears you clap) and downs blood disguised as red wine. You'd think a sister of a vampire slayer would smell some fish, but nope. At least, not until Kazaf tells Helen about his identity. But alas, Juliet loves Romeo anyway despite his less-than-typical diet...

Kazaf The Light Prince (Edison Chen)
The fifth prince of Vampireland who can be seen as either the wimpiest vampire since Count Dracula or the most good-hearted one to walk the dark streets. You see, Kazaf refuses to suck blood from victims' necks and instead drinks blood from wine glasses. Of course, we can all conveniently forget the fact that the blood must come from somewhere, whether from Kazaf's servant-aid Prada (played by a deliciously cast Anthony Wong) or from Papa King who probably has dozens of servants to do the dirty deed and mail the blood back to his fifth heir. Anyway, Kazaf moves into a church in Hong Kong (probably the most ironic of ironies) with Prada and begins a sweet relationship with Helen. He also suscepts to near-famine when his food supply runs short as Helen rushes him to a hospital to steal blood. Not only this, but all is not well in Vampireland. Duke Dekontes, Kazaf's uncle, is after the throne and has killed the other five princes. He is now after Kazaf, the last remaining heir whose "inner stone" must be possessed in order to open Day for Night, the vampire bible that bestows the ability to hunt during the day (i.e. become The Ruler of Vampireland)...

Gypsy The Reeve Groupie (Gillian Chung)
Reeve's new partner-in-hunting who also happens to idolize-love Reeve. Never mind the fact that their pairing's just creepy as ever. Of course, Reeve remains passive to Gypsy's affections due to his aforementioned vow despite the fact that she cooks, cleans, and irons for him. Of course, Gypsy does not get along with Helen, and the two have a ridiculously hilarious fight over a teddy bear complete with unfeasible acrobatics and hops on the walls. But then, of course, the two bond. This is a movie with the Twins, for crying out loud...

Summary:
"The Twins Effect" is the latest actioner from EMG, producers of the forthcoming US$40m Jackie Chan blockbuster 'Highbinders', and was shot on location in Hong Kong and Thailand.

Ace vampire slayer Reeve (Ekin Cheng) tracks his arch-enemy, the Duke Dekotes (Mickey Hardt) to Hong Kong. The Duke is hunting for Kazaf (Edison Chen), the fifth prince of the vampire nation. With Kazaf's blood and the ancient vampire bible, the Duke will bring a new age of darkness. On arrival, Reeve learns that he has a new partner, a feisty but inexperienced young beauty named Gypsy (Gillian Chung). Matters are further complicated when Reeve's innocent younger sister, Helen (Charlene Choi), develops a romantic relationship with Kazaf. With all the odds against them, our heroes get some unexpected help in the form of high-kicking paramedic Jackie Fong (Jackie Chan). In a high impact final reel, Reeve, Gypsy and Helen join forces to fight the Duke and his minions¡K

I think...
Such a cool movie ^-^ I really love Edison Chen's movies.. hehe! He's so cute here.. This movie is very suspense and funny at the same time. The twins here are very hilarious.. hehe! They were fighting here when Gypsy arrived at Reeve's house. It's because Helen is Reeve's sister. Am I right? hihi! I really like Gillian Chung's beauty, she's soooo pretty!
Prada in the movie is very hilarious too.. He's the assistant of Kazaf, I think. He's in the first picture with Kazaf.
I was wondering what's Jackie Chan doing in the movie. He's playing a very short role and he's the groom of Karen Mok in the movie.. lol! :)
