The ship at sea is the same miniature model used for Titanic (1953), which in turn was used for Gli uomini preferiscono le bionde (1953) and Traversata pericolosa (1953). The interiors of the dining room and staircase on the ship were also from the same movies.
Herb Ellis, Barney Phillips and Jack Kruschen (who appear as police detectives) were frequent collaborators with Jack Webb on Dragnet.
