Boy, Did I Get a Wrong Number! (1966)

The Divine Didi, a European actress known more for her bubble bath scenes than for her acting, decides she has had enough with bubble baths and wants to be taken seriously as an actress. So-much-so that during the filming of a bubble bath scene, she runs away and winds up in Oregon. While staying in a hotel, the operator accidentally connects her with real estate agent Tom Meade trying to reach his wife at a beauty salon. She asks him to bring her some food. When he does, he suggests she go to his remote, hard-to-sell cabin in the woods to continue hiding from Hollywood and her director/boyfriend while increasing the sales value of the property. She agrees. Now Tom must keep the secret, especially from his wife Martha and from his suspicious housekeeper Lily.
