Alfred Hitchcock's last silent film.
A signatory on the fishermen's petition against steam trawlers is Jack Cox. Jack E. Cox was Hitchcock's cameraman on the film.
Two key lines in the film have no intertitles, the viewer having to lip read them. About 64 minutes into the film, Kate reveals to Philip "Philip, I am going to have a baby." 4 minutes later, she reveals to her husband Pete "I am going to have a baby."
