Sammy Sum (沈震軒) was topless and filmed a fighting scene with foreign fight choreographer, Chris Collins in a ship for a new film in Tuen Mun on 24th January 2019.

Sammy revealed the opposite party hit him with a glass bottle (props) and assumed it was wine when shooting a fighting scene a few days ago. His manager believed there was something wrong and the staff realised it was blood oozing from his head. However, there was no first-aid box at the scene and fortunately, Chris helped him to disinfect the germs and apply plaster by using his knowledge in US army previously. Sammy resumed the shooting quickly and the doctor told him he did not need to go for stitches, but would form a scar though.
