Visit to HK

I'm planning a trip to Tokyo for next Summer (need to start planing well in advance) and hope to hop over to HK (only for a couple of days though). Over the course of the next 4 to 5 months, I'd like recommendations of things to do and places to see. I hope to get a chance to take in a movie at the theater.<br>I'm open to all suggestions/recommendations.<br>Thanks.<br><br>
