My wife and I have been struggling to come up with the name of the cute romantic comedy where ... a man's wife is shippwrecked on an island for 7 years. She is rescured and comes back to find that the husband is remarried to a "not very nice" woman and the kids don't remember their real Mother. She tells her husband that the man that she was shippwrecked with was a geeky accountant type but he was actually a beefy hunk. The husband is still madly in love with her and tries to hide the discovery from his current wife, yet struggles to find the truth about wife #1on the island. I seem to recall that the husband was Cary Grant, Rock Hudson, or some big star like that. Wife #1 may have been a big star too and had a talent for comedic delivery. It is a cute movie and I seem to recall that it was remade a few times. Can anybody help us figure out the title?
