According to an article in Asian Pop News, both actors Louis and Sean regularly went swimming and running as they personally took on the stunts and action scenes in the movie. Louis described his time filming as being that of a physical challenge. During filming, his palm was injured and an old ankle injury was aggravated. "I filmed lots of risky stunts as as flying, diving and shooting, if you do not have the stamina, it would be very hard to manage," Louis said. "I was very lucky i did not suffocate or have a stroke during filming. I felt satisfied that I was able to take on the stunts personally," he added.He also revealed that filming was done in a studio with little ventilation, citing temperatures as high as 40 degrees Celsius."Everyone was perspiring and it was like it was in a sauna," he said.
