Mr. Belvedere

Clifton Webb was one of the actors I really enjoyed from the studio era. He starred in several very good films, including Laura, one of the best films noir, another noir I liked was The Dark Corner, there was a World War II thriller, The Man Who Never Was (based on the Mincemeat plot), and he starred in many others. I also enjoyed him in his Mr. Belvedere comedies. The first of that series was Sitting Pretty (1948), and then Mr. Belvedere Goes to College (1949), Mr. Belvedere Rings the Bell (1951), and Mister Scoutmaster (1953). Each of them can provide an undemanding, enjoyable, afternoon or evening.

Wikipedia's description of the plot of Sitting Pretty (which I intend to watch again tonight):

In the suburban Hummingbird Hill, lawyer Harry King and his wife Tacey have trouble retaining a nanny for their three young, rambunctious boys: Larry and Tony, both of whom get into frequent mischief with the family dog Henry; and baby Roddy. When the latest in a string of servants (all women) quits, Tacey advertises for a replacement and hires Lynn Belvedere sight unseen. However, she discovers that Lynn Belvedere is actually a man upon his arrival, a mysterious one with many skills and achievements – and who declares himself to detest children. Nonetheless, the Kings reluctantly agree to a trial period during which Belvedere quickly wins over the boys. However, his mysterious nature intrigues both of their parents, and Harry becomes annoyed by his condescending attitude. ....

In the meantime, we learn that Belvedere has spent the past few weeks secretly researching and writing a salacious account of the goings-on among the residents of Hummingbird Hill. In fact, the book's blurb describes it as "a screaming satire on suburban manners and morals". The published tome becomes a national bestseller, upsetting everyone in the community. ....
