Agreed. That's one thing that always amazed me as to how the sh*t she won an ACADEMY AWARD for 'THE COUNTRY GIRL'. GRACE KELLY was a very good actress, but she, just like KATHERINE HEPBURN, had the limitation (because of their actual backgrounds ?) of not being able to credibly convey portraying anything less than upper middle, or upper upper class ladies.

It is believed that Grace Kelly won her Oscar for "The Country Girl" because, among other reasons, she was in FIVE movies in the single year of 1954: the great "Rear Window" for Hitchcock, "Dial M for Murder" also for Hitchcock, "The Bridges at Toko-Ri" with Bill Holden, jungle action-adventure "Green Fire" (the one loser of the bunch), and "The Country Girl" in which she played plain and dowdy, so that's the one they gave it to her for.
Meanwhile: Shirley MacLaine made a sparkling debut for Hitchcock in "The Trouble With Harry." Much of what would make her a very big star in the late 50's and 60's was right there from the beginning: her sexy-impish manner, her wit, her intelligence. She'd consolidate her stardom with "Some Came Running" (doomed Rat Pat Floozie) in 1958 and "The Apartment" (suicidal elevator girl love goddess of good Jack Lemmon and evil Fred MacMurray) in 1968.
And MacLaine is STILL a star today, fully 50 years after "The Trouble With Harry." (That "Terms of Endearment" Best Actress Oscar came in between.)
Ironic, isn't it? All those great Hitchcock Blondes, and arguably the most major Hitchcock actress still working today was the "Hitchcock Redhead."
