While shooting Clint Eastwood's (Will's) only scene, Rock Hudson noticed that Eastwood was wearing prop glasses. Hudson protested that because he was playing a physician, he should be wearing glasses, so Director Jerry Hopper gave Eastwood's glasses to Hudson. It is the only scene in this movie where Hudson wears glasses.
Concerning his participation, Douglas Sirk said in an interview with Jon Halliday in 1971 that he did some work on preparing this movie, that he brought over Cornell Borchers (Lisa Gosting) from Germany, and that he re-shot scenes with George Sanders (Victor) on the latter's and the studio's request.
Final film of Betty Chay.
