Rock Hudson in Pillow Talk (1959) and Lover Come Back (1961)
While we don't get to see what the
the way he slips into his southern drawl effortlessly; his interaction with Tony Randall... It's criminal that he wasn't nominated by the Academy Awards like Doris was for her role in this film. While LCB's "Linus" is supposed to be an innocent, "Rex" isn't quite that extreme. Instead, he is just a polite, kind, considerate gentleman -- you know, like Brad should be. By film's end, we're supposed to believe that is what he has become, minus the Texan accent.
P.S. If you feel like having a good cry, you can watch Doris Day's tribute to her friend here, made in 2014 when Hudson was TCM's Star of the Month.
