Wader Studio / 華達製片廠 [1950-1970]
Wader Studio was located on Castle Peak Road of the current Kwai Fong, Hong Kong. The location marker is approximate*. The source listed below show that the company produced films during the period 1950-1970.
*Edit - October 3, 2017 - as per philk's advice, I have moved the marker a bit north to the general vicinity of Block B and Block C of the current industrial centre by the road. Thanks.
