(written from a Production point of view)
According to the Star Trek: The Next Generation Companion, Luke was briefly considered for the role of Doctor Noonian Soong in the Star Trek: The Next Generation episode "Brothers" when it was thought having Brent Spiner play three roles in the episode would not be feasible.
Luke was born as 陸錫麟 (Luk Sek Lan or Lù Xílín) in Guangzhou, China. His family emigrated to the United States and settled down in Seattle, when he was a child. He became a naturalized US citizen in 1944. He is most recognized for playing Charlie Chan's #1 son, Lee Chan, in several Charlie Chan films throughout the 1930s and 40s. He's also known for portraying Kato in the original Green Hornet film shorts of the 1940s. He is also remembered for his role as Master Po on the 1970s television series Kung Fu.
He played the role of Mr. Wing in the 1984 Joe Dante film, Gremlins, and its 1990 sequel, Gremlins 2: The New Batch. Fellow Star Trek alumni Zach Galligan, Dick Miller, Kenneth Tobey, and even composer Jerry Goldsmith appeared in both of these films, while Jonathan Banks and William Schallert appeared in the former and Robert Picardo, John Glover, Henry Gibson, and Ron Fassler were in the latter.
