Mr. French and now Miss Beadle. Its like who is going to be who in Hollywood.

Was this show a jumping off point for a lot of careers? Was it low in the ratings so anybody and everybody could play their hand at acting on it?

The show finished at #13 in the ratings the season Sebastian Cabot came on as Professor Tom Morrison (S5). Pretty strong ranking, considering TV in the U.S. still had variety shows, westerns, and military shows in those years. Mrs. Morrison, played by lovely Doris Singleton, becomes the mother-in-law of Mike, and years later (in Season 11) Doris plays Chip's mother-in-law (as Mrs. Williams, Polly's mom)...!

Here are the season-by-season ratings:

1 #13
2 #11
