The above pictures are of the junction with Hollywood Road above. The antique shop with the round door/window is still there. The shots below though I'm not so sure - I think they might be the part of Ladder Street that joins with Caine Road - however, the block at the back has recently been redeveloped so I can't confirm.
However, if I'm right and the above bit is the Caine Road section, then this bit below, where the steps get quite wide, could be the section of Ladder Street between Caine Road and Bridges Street.
Anyway, after all that the sequence ends up back at the junction with Hollywood Road with Man Mo Temple making yet another film/TV appearance. I think it must be one of the most-filmed places of worship in HK.
