I liked him in Darling Lili too, but I watched it, because I have had a huge crush on Julie Andrews for decades. I especially liked her singing The Girl in No Mans Land.
I’ve never seen Darlin’ Lily. I love Julie Andrews. So pretty, so talented. I am late to admiring Rock Hudson’s work - although I always liked him in Giant. My husband (an actor) insisted I sit down and watch his work in the Doris Day movies. He was right, as always.
