We can see the Kowloon Rail terminus (now Hung Hom Station) at the back left - it's the white building with the slanted white floors. Of course the KCR track runs north from there and we can just see a KCR train (now East Rail) heading away towards its next stop at Mongkok (East). The reddish brick building on the right is northern end of the Polytechnic University.
Chatham Road North can be seen running left to right. Luckily for us, there is a picture on Panoramio that is an almost exact copy of this same angle (which is why I think it was filmed from Chung Hau St) courtesy of user joeyuenasap. See below.
It's nice to see that the old buildings on the left in the screen grab are still around but have been given a bit of a lick of paint. But lots more development in the meantime including new buildings at the PolyU and the large flyover above the track which joins Cheong Tong Road South onto Princess Margaret Road above the Hung Hom Interchange.
