Sir Bygber: I should think Joi Lansing is one of the foxy gals running around with Rita Moreno in SINGIN' IN THE RAIN, or one the chorus girls in Debbie Reynolds' "I Dream of You" number.
Like Gwen Verdon, who appeared unbilled in a number of pretty good musicals before she made it big on Broadway with #### Yankees, Lansing really stood out in a number of films, with or without dialogue. And if she had a couple of good lines or a good angle, she could easily steal a scene, as she did from Dean Martin and Tony Curtis in WHO WAS THAT LADY (Sidney, 1960).
Unlike Verdon, she never was recognized for talents other than her beauty.
As an aside, James Elroy (LA CONFIDENTIAL) has a supposedly-true crime essay, which claims that Joi Lansing had a sister, also a model, who was murdered by a serial killer, about the time his own mother was. He has an additional soft spot for "The Lansing Sisters" because they come from Salt Lake City, where he now lives.
What an old pal used to call "a nice-to-know, if true."
