Kam Kwok Theatre - Front

This picture was not Kam Kwok Theatre, but probably Majestic Theatre (大華戲院) of Singapore in 1964.

1. Kam Kwok Theatre was established in 1966, but the movies “Lover's grief (工廠玫瑰)” and “The past love/ I did my best (情至義盡)” were released in 1964.

The 1966 movie "The Golden Gun 金手槍" was showing.

https://hkmdb.com/db/movies/view.mhtml?id=4618&display_set=big5

The movie was showing end of 1966 to beginning of 1967. A 1967 newspaper advertisement confirmed Kam Kwok theatre was showing the movie:

As a matter of fact, golden gun was only the next movie to be shown. The current movie showing was 孝女珠珠 (1966)
The Dutiful Daughter Chu Chu
Alias: Dutiful Daughter
beginning 12/20/1966

According to hkmemory.hk, the address was rather  4639 section of Junction road九龍橫頭磡聯合道4639地段 whatever that means. But the 1971 map seems showing the theatre at the south-east corner at the junction road-Heng Lam road junction. And the building on the left side of the above picture looks like a block of the Lo Fu Ngam Resettlement Area assuming the theatre was facing the junction road.

A 1970s picture showing the same area with the bus stop in front. The Lo Fu Ngam Resettlement on the left side. There was a second floor kindergarden called ai wah kindergarden or 愛華幼稚園 at 176 junction road. The google map still show that kindergarden which has since closed down.
