"Making Trouble in the Studio" is a 1926 animated film directed by Wan Guchan, with voice participation by the Wan brothers and produced by the Great Wall Film Company. The film depicts a painter working in his studio when suddenly, a small figure in traditional Chinese clothing that the painter has drawn leaps off the canvas. Mischievous and comical, the little character causes quite a bit of trouble for the painter. After a series of chases and scuffles, the figure is finally driven back into the painting. Although the plot is simple, the Wan brothers, who were creating animation for the first time, encountered numerous challenges. During filming, either the parts that should move remained still, or the parts that shouldn't move moved uncontrollably. It was only after multiple trials and continuous experimentation that they succeeded in completing the film. This work is also China's first animated film to feature both live-action and animation simultaneously. In the film, the painter is played by Wan Guchan, while the little paper figure is animated. Through the creation of "Making Trouble in the Studio," the Wan brothers truly mastered the key techniques of animation production, making it a milestone in Chinese animation history. The film was produced by the Great Wall Film Company and has a runtime of 12 minutes.
