Man of Tai Chi - Keanu Reeves (2013) - Electrical & Mechanical Services Department, Kowloon Bay

The exterior of the Police HQ was also filmed in Kowloon Bay, at the new Electrical and Mechanical Servies Dept building on Kai Shing Street. Obviously the signboards are fake. The large column centre screen is actually one of the uprights for the Kwun Tong Bypass. Apparently,this building wasn't new and was originally the air freight terminal for neighbouring Kai Tak Airport. It must've undergone a significant refurb to make it ready for the EMSD once they moved from their previous, shared location on Caroline Hill (edit 2023: which incidentally, is now demolished).
