Q: Remember that part in the Mary Martin version of Peter Pan where Mary Martin-as-Peter Pan "pretends" to be a woman and Captain Hook thinks she's hot except she actually is a woman pretending to be a little boy pretending to be a woman?
A: Yes! PANCEPTION. Also, the song "Distant Melody" still makes me teary, FYI.
+1: Remember the ostrich with woman legs in this movie? That's Joan Tewkesbury, who cowrote screenplays with Robert Altman.
Have at it.
