Turner Classic Movies was running A MAJORITY OF ONE (1961) earlier today and I just happened to come across it in the middle. In the film, Alec Guinness, under heavy makeup, plays a widowed Japanese man who has a relationship with a middle-aged American Jewish woman played by Rosalind Russell.
In the scene I stumbled on, there was a genuine Japanese-American actor playing Guinness’s Japanese-speaking son. He was none other than George Takei, as seen in this still:
Takei, of course, went on to play Sulu, the helmsman on board the U.S. Starship Enterprise, on the original “Star Trek” TV series, as well as six subsquent Star Trek movies.
Guinness, of course, went on to play Obi-Wan Kenobi, the famed Jedi Knight in STAR WARS (1977).
So who else knew that Sulu was the son of Obi-Wan Kenobi?
