Not filmed in Manila but in Thailand. The skycrapers are clearly in Bangkok. There is no tuktuk in the Philippines and it's not a right-hand drive. Very dissapointing since the Philippines have Goethe-Institut Philippinen and there is a deutsch school in Davao City in Mindanao where the setting (both Basilan and Isabela City are in Mindanao) is located. Clearly they picked Thailand to shoot since the production team as well as the extras (other people behind and on camera) and other human resources are very much cheaper to exploit compared to filming it in the Philippines.
