Tony Leung stars in a unique indie film, playing a character written especially for him by director Ildiko Enyedi. The film's central theme revolves around a ginkgo tree, and Leung's preparation for the role involved extensive research into neuroscience and botany. Enyedi's decision to write the part for Leung was influenced by his versatility and a special quality she perceived in his interviews. She sought a strong, open presence without shields or defenses, akin to a monk's calm and cheerful openness towards the world, and a deep faith in oneself.
Leung's character, a neuroscientist, studies early cognitive development in babies. To prepare, he delved into books and consulted experts, even hiring a British coach to add a slight British accent. This meticulous preparation allowed him to fully immerse himself in the role, believing he was indeed a neuroscientist. The film's focus on the ginkgo tree, a resilient and adaptable species, reflects the scientist's ability to thrive in unfamiliar environments, much like Tony Leung's own approach to loneliness and solitude.
The movie has significantly altered Leung's perspective on the world, fostering a deeper respect and awareness for plants and nature. He now views trees as sentient beings, with intelligence in their own unique forms. This newfound appreciation for the natural world has led him to reconsider his actions and their impact on the environment, marking a profound personal transformation through his involvement in the film.
