The Angel Strikes Again - Lily Ho (1968) - Hollywood Theatre, Mongkok

Someone posted online somewhere (can't remember where) that they were really impressed with the street mockup used for the cinema sequence in this film. Granted, much of the on street sequences were filmed on the (very obviously) fake Movietown lots, however, the cinema sequence was shot at a real place. It was the Hollywood Theatre on the corner of Sai Yeung Choi Street South and Soy Street. The cinema is long gone (it closed in 1980) but note that at the time of filming it was showing the 1967 Shaw film, Susanna (Chinese title: 珊珊). Hollywood Plaza stands on the site now (not to be confused with "Plaza Hollywood" above Diamond Hill MTR station).

This is where agent 009, posing as a buyer, agrees to meet the gang to pay for some explosives. 

This last image is great because it shows the view looking south down Sai Yeung Choi Street South, with Soy Street crossing in front. In the distance is part of the old Kwong Wah Hospital site.

T.N.T Jackson - Jeanne Bell (1974) - Hollywood Theatre, Mongkok

Staying with T.N.T Jackson, Rodney also identified a location I hadn't put up a screencap for but was looking for anyway. He's a mindreader!

This is the movie theatre that Stan Shaw supposedly goes into. The establishing shot used the exterior marquee of the Hollywood Theatre, located on the corner of Soy Street and Sai Yeung Choi Street South. So, actually right next to the previous post. I suspect, but can't confirm, that the cinema interior used in the film was actually one in the Philippines where much of this movie was shot. I say this because it looks far too big to have been a Hong Kong cinema and many of the extras appear to be Filipino rather than Chinese.

In what appears to be an informal convention in Hong Kong, the cinema's name is remembered by the building that replaced it - 'Hollywood Plaza'.

Again, here is Rodney's comment:

Right after the second screencap, Charlie (Stan Shaw) walks into the Hollywood Theatre on Sai Yeung Choi Street and Soy Street. The word "Soy" on the street sign attached to the exterior of the theatre is (barely) visible when the camera shows Charlie looking up at the billboard for the Shaw Brothers film 'The Golden Lotus'[金瓶雙艷].

IMDB does not list any filming dates, but 'The Golden Lotus' premiered in Hong Kong January 17 1974.
