I saw this movie as a kid late at night after everyone in the house was asleep. I liked the title, "Mrs. Mike," because Mike was and is my name, and I thought it'd be nice to entertain what a "Mrs. Mike," a wife for Mike, might look and act like. And I liked Dick Powell. And though I remember the dramatic part of the story regarding the diphtheria epidemic, I'd forgotten or overlooked how it was really about the shortages of vaccine serum. The acting and script were terrific. Loved the backdrop of a Canadian forest, canoeing across deep forest lakes and rivers and the struggle for life between the Mike and his wife, Kathy. The cynic in me says that Dick Powel was made a star because he supported key industries, like the vaccine industry, but like I said, that's the cynic in me. I hope I am wrong.
