According to MX News Bites, it's the story of "two celebrated artists as they publicly announce their marriage, much to the delight of audiences and fans who have been following and rooting for their much publicized romance. However, as the story unfolds, what goes behind the camera seems to differ from what the public witnesses."
The producers are in talks with real-life celebrity couple Christopher Lee and Fann Wong to star. It is slated to open in Singapore during Chinese New Year in 2009.
Update: Variety has a story, with quotes from Ekachai:
There are four main characters, the couple and their managers, plus a number of cameo appearance. We are just finishing the paperwork for our two stars and are looking at some regional casting too. As we've done all the location scouting and their talent availability is set we should be good to go from mid-November."
