Lana, Kim or Lee
Lana Turner was supposed to play the wife but left the film after a row with Otto Preminger who claimed La Turner was miffed at the wardrboe assigned. Jean Louis was the head designer at Columbia and would have crafted an appropriate wardrobe and Lana was quoted as saying "I Would Never Leave A Picture" for such a trivial matter as Costume"
James Stewart worked with Kim Novak then the biggest star at Columbia on Bell Book and Candle and on Kim's loanout to Paramount for Vertigo, and Otto Preminger directed Kim so well on her loanout to RKO for The Man With The Golden Arm. In short Stewart and Novak and Preminger and Novak remained life long friends, one wonders why Preminger did not cast Novak in this film; the only reason I can think of is that Kim was working on another film.
Lee Remick did a good job as the Wife and Preminger noted he wanted her even before Lana was cast and one wonders if he chased Lana Turner off the film over the costume row.
Lee Remick raised eyebrows years later when she took over Marilyn Mornoe's part in Somethings Got To Give after Kim Novak, Doris Day and Shirley MacLaine all turned that part down due to deference to MM. As we all know Marilyn eventuallyw as rehired by 20th.
