He then signed up for the international movie production "Dance of the Dragon" (2008), a love story that mixed ballroom dancing with martial arts action and costarred Singaporean actress Fann Wong. He won the Best Actor award at the inaugural West Hollywood International Film Festival for his role. Jang also made a cameo in Japanese drama "Ryokiteki na Kanojo", a remake of the 2001 Korean film "My Sassy Girl". After his earlier guesting on star Tsuyoshi Kusanagi's talk show, the director of the drama reportedly added new scenes for Jang that were not included in the original script. Jang then appeared as the love interest in three music videos of Taiwanese singer Elva Hsiao.
