Singapore YouTube personality Dr Jia Jia has landed himself a supporting role in an upcoming Chinese movie based on a hit animated television series, Xi Yang Yang Yu Hui Tai Lang (Happy Sheep And Big Grey Wolf).The seven-year-old, whose real name is Chua Jin Sen, will play Xiao Hui Hui, the clever son of the main character in the movie called I Love Wolffy, which revolves around a wolf who is tasked to find a gemstone in order to retain his position in a wolf clan.The Straits Times reported that the movie is a mixture of live action and animation - the animated wolf characters are transported to the real world where they take human form.It is a collaboration between children's content producer Mr Cartoon Pictures from China and local motion picture production and distribution company 9 Harbors International.They initially had no intention of casting a Singaporean. But the film's producer Raymond Tan, 39, felt that a local should be cast in the movie as it is being filmed here. They were looking for a child actor and Mr Tan immediately thought of Jin Sen, a Primary 2 pupil at Maha Bodhi School.Mr Tan says: "His appearance is very likeable. Although they did not get all the Singlish jokes in the Dr Jia Jia videos, they liked his facial expressions - he is very natural."This will, be Jin Sen's second movie project after the local film Taxi! Taxi! (2013), in which he starred as the son of a taxi driver played by Mark Lee.His mother, housewife Caren Chua, 44, says: "We noticed from the first film that he has a lot of interest in acting. There will be a lot that he can learn from shooting a movie that he cannot learn in a classroom."She does not know how heavy the filming schedule is yet.Filming will start here on Monday. It is expected to last for one month and will take place at local attractions such as Sentosa and Science Centre Singapore.This will be the second live action movie based on Xi Yang Yang Yu Hui Tai Lang. The television series has been running for about eight years.
