Her screen debut was in 1977 in Peter Bogdanovich's The Last Picture Show. I love that movie. Ben Johnson was a standout. I also enjoyed the sequel Texasville. [It's difficult to locate now]
There was racy nude scene (for 1977) that shows Cybill stripping in an initiation. I like it because she is wearing a girdle, de rigeur for 1951, the period of the movie. Nothing like a girdle on a girl who does not need one.
Would have loved to hear a paddle smacking her girdled bottom
