The Man Who Knew Too Much (1956 Alfred Hitchcock)

Doris Day holds her own, as evidenced by long takes between her and James Stewart. John Michael Hayes wrote it, with Angus MacPhail, and it's Bernard Herrmann's only appearance on film (though ironically, he isn't conducting his own music).

We were having a fifties day.

With Brenda de Banzie, Bernard Miles, Alan Mowbray, Daniel Gélin, Reggie Nalder (assassin).

Scene in taxidermist's is hilarious.

"I think, actually, the difference would be in the first The Man Who Knew Too Much I wasn't audience-conscious, whereas in the second one, I was."

It somehow seems extremely incongruous to see Stewart and Miles in the same scene...
