I just noticed this featurette on my DVD of Charlie Chan at the Race Track. It is 15 minutes long and is narrated in part by Keye's niece Vikki Luke. It gives us a brief history of Keye Luke's career in the movie industry. He actually started out as a highly accomplished commercial artist who worked for several film studios. He became an actor by accident when he was doing some artwork for the Greta Garbo '34 film The Painted Veil and was asked to read some lines for the not-yet-cast role of Shay Kee Seng. Luke's reading was perfect, he got the part, and the rest is history.
There are some stills from Luke's performance in Flower Drum Song that I have never seen before. Vikki Luke also provides some information about Keye's participation in the national tour. We are also shown several photos of Vikki's family. In addition she mentions her husband and his family but doesn't actually give us their names.
Have you ever seen this documentary? If not, it's worth checking out.
