A Guest in the House is an involving psychological melodrama, well directed and acted, concerning a young woman's obsessive love. Evelyn (Anne Baxter), an emotionally vulnerable and unstable woman, stays at the home of her doctor Dan Proctor (Scott McKay). There she meets and falls in love with his brother, Douglas (Ralph Bellamy), who is happily married to Ann (Ruth Warrick). Evelyn then sets forth to break up the happy marriage and win the love of Douglas -- with tragic results. A Guest in the House directed by John Brahm, aided by Andre De Toth and Lewis Milestone, who are uncredited, is a sensitive, well-acted melodrama. Baxter gives a fine performance as the unstable young woman, who cannot overcome her obsessions. The fine musical score, composed by Werner Janssen, was nominated for an Academy Award.
