Here's why that might be:
* Limited English-language information: Information on Thai entertainment industry figures is often more readily available in Thai language sources.
* Not a major international star: It's likely that Pisamai Wilaisak is not a major international star, meaning there may be less information readily available in English.
* Privacy: Actors may not choose to make their entire filmography publicly available.
How to find more information:
* Search in Thai: Try searching for her name in Thai language online sources, using Thai search engines like Google Thailand (google.co.th).
* Use Thai entertainment websites: Explore Thai entertainment websites and forums.
* Check IMDb: While IMDb may not have detailed information, it might list some projects she has been in.
Please note: without more information, it's challenging to provide a complete list of her projects.
