SPL - Donnie Yen (2005) - JC Studio, Clearwater Bay

Speaking of JC Studio, as I just was, the canteen scene where Chung (Simon Yam) tells Lo (Dick Liu - who passed away in March this year R.I.P) that he has a brain tumour was actually a room in JC Studio. It's possible that other scenes were filmed inside the studio building (such as the hospital scenes) but this is the only one I can confirm for certain.
