I was 17 when this film was released and having fallen in love with Doris Day when I was 11, I was first in the queue. It is a wonderful, wacky film of the mid sixties and Doris Day and Rod Taylor are perfectly matched. The story is a simple case of mistaken identity when Doris is mistaken for a spy at the space centre where she works and Rod Taylor is a scientist. The glass bottom boat of the title is run by her father and provides a seperate focus for the story. The title song and Que Sera Sera are beautifully performed and do not detract from the comedy element of the film. I am submitting this today as I have just seen the film again on TV and it has lost none of its charm.
