'Cabaret' connection?
The stage origin of the musical "Cabaret" is the 1951 play "I Am a Camera" by John Van Druten.
Julie Harris starred and dazzled as "Sally Bowles" (MUCH different than Liza but a captivating performance nonetheless).
Maggie McNamara comes off in "The Moon is Blue" as a wholesome virgin version of the character of "Sally", replete with so many observations on the relationships between men and women - yet seems to have the same energy as Julie Harris' performance (which is available on film).
I can't help but wonder if some - or all(?) of Maggie's acting was inspired by Julie's.
You watch both - you tell me.
"Don't call me 'honey', mac."
"Don't call me 'mac'... HONEY!"
