Gallen Lo & Maggie Cheung Ho Yee
Collaborations: 6Gallen and Maggie have worked together in four series ("Cold Blood Warm Heart", "Mystery Files", "Old Time Buddies", and "Old Time Buddies - To Catch a Thief"), one musical ("Old Time Buddies Musical"), and one movie ("Those Were the Days"). Their most classic pairing would have to be the "Old Time Buddies" series, where they played Lee Kei and Ching Bo Chu.
Kwong Wa & Anne Heung
Kwong Wa & Melissa Ng
Okay, that's all of the 'Best Onscreen Couples'. KW & Anne & Melissa are on the list because they have filmed so many series together. Once a male artiste and a female artiste start to pair up in their first series together, the number of times they will pair up again would be endless. The audience will love them, and then TVB will continue to pair them up or cast them in the same series. Bobby is now filming another series with Yoyo, and this is their third collaboration. Bobby and Ada have filmed three series together. Kevin Cheng and Niki Chow: four times. Bosco and Tavia: three times. Ron/Kate, Ron/Shirley, and Ron/Toby Leung: two times. Steven and Bernice: two times. Melissa would have worked with Sunny in four series together, but she has turned down ??? and ????. Bowie and Gigi are going to be in four series together because the both of them are cast in Chik Kei Yi's 80-episode long drama.
It wouldn't kill TVB to have different pairings, will it? Steven has been pairing up with the younger generation of female artistes. I would love to see him pair up with Anne or Yoyo. He and Anne showed great chemistry on the game show "Trio Delights". Steven and Yoyo actually filmed a movie together back in 2000, but that was a long time ago.
I have already complained about TVB pairing up onscreen couples according to status and not compatibility or matching, but the pairings are just too repetitive now. There is no freshness or surprise anymore. TVB is just playing it safe by saying, "Since a couple has been paired up once and they were well-accepted, let's pair them up again". Duh!
