Sung Kang plays the character of Han Seoul-Oh. The character's last name has been revealed in Fast Five (2011) as a result of a facial recognition software match. This is a reference to Star Wars: Episode IV - A New Hope (1977) and its sequels that feature a character named Han Solo, played by Harrison Ford. However, both actor Sung Kang and director Justin Lin who has also served as a producer on some of the Fast and Furious movies have stated that "Seoul-Oh" was an alias. Han's real full name is apparently Han Lue. Han Lue was played by Sung Kang in Better Luck Tomorrow (2002). The movie was directed by Justin Lin. Therefore, Better Luck Tomorrow (2002) is a prequel to the Fast and the Furious series, as revealed in an interview with Justin Lin.
