You have grasped the similarities between Tamar Park and HKU Happy Park. It would be nice if you have pinpointed specific locations to shoot as it is crucial to find a place with almost no greenery to mimic Happy Park. To film in a public area managed by the government, you will need to apply to the Film Services Office 10 weeks before, which the producer should pay attention to. Moreover, I would question if adding blue/ green light would help with simulating the atmosphere of Happy Park. It might create a mysterious/ studio-like effect instead. Regarding the use of CGI, have you considered utilizing establishing shots (shooting HKU/ Happy Park without actors, perhaps long shots) so to let the audience believe that you are actually filming HKU? Rebuilding 3D models of HKU might be time-consuming and unreal. Also, you might bring HKU posters to Tamar to make the environment more campus-like. Overall, it is quite creative that you have selected Tamar Park to mimic Happy Park. It would be great if each role could be more specific about his/ her job duties.
