Fonda and Bacall's 'hip' dance moves

I hadn't seen this movie for many years and just found it on TCM in the wee hours. I really enjoyed the movie, and I thought the casting was pretty clever. The anniversary party scene for "Frank and Sylvia" was cute and corny. I don't think I've ever seen dancing quite like the unusual "Twisting" of Henry Fonda and Lauren Bacall. I enjoyed the references to Jack Lemmon too, a cute reminder of the classic comedy, "Some Like it Hot".
Natalie Wood and Tony Curtis both brought a light touch to this comedy, that is representative of sex roles of the time with a little hint of the future.
