永久居留
Hung has appeared in several films, and in 2009 took the joint-lead role in "Permanent Residence", playing the character Windson alongside Sean Li. He also sang the track "Truly Madly Deeply" for the same film. The story is an unconventional choice of subject matter for Hong Kong cinema in both its examination of male homosexual love and the marital strain resulting from self-denial of that love; it examines the 'limits of life', while the second in the trilogy, Amphetamine, explores this theme further in the 'limits of passion'. The third, as yet unreleased, film in the trilogy, "Life of an Artist", examines the 'limits of art'.
