A new bride (Jeanne Crain) and her husband (Carl Betz) set sail on an ocean liner for a transatlantic honeymoon. But when her husband disappears aboard ship, no one claims to have seen him and any evidence of his existence has evaporated. Is she mentally unstable or are there more sinister forces at work? Based on the 1943 radio play CABIN B-13 by mystery writer John Dickson Carr and directed by Joseph M. Newman (THIS ISLAND EARTH). It may be a low budget programmer but director Newman does wonders with limited production values and confined spaces and Crain and Michael Rennie as the ship's doctor prove persuasive leads. While the "husband/mother/companion disappears and no proof of their existence" plot is hardly fresh, the movie provides a menacing and paranoid atmosphere (I don't think any movie has made foghorns sound so threatening) and the fetching Crain plays hysteria nicely. With Mary Anderson, Max Showalter, Willis Bouchey and Marjorie Hoshelle.
