Love Crazy (1941)

William Powell and Myrna Loy re-team for this (literally) crazy screwball comedy about a happily married couple who, thanks to a visit from mother, find their marriage on the rocks and the husband committed to a mental institution. Poised to celebrate their fourth wedding anniversary, Steven (William Powell) and Susan Ireland (Myrna Loy) find their domestic bliss shattered by a visit from Susan's mother (Florence Bates). Susan's mother sprains her ankle and extends her visit, just in time to draw the wrong conclusions when her son-in-law pays a friendly visit to his old girlfriend Isobel (Gail Patrick). Susan's mother eavesdrops and reports it all to Susan, who in a jealous rage tries to make Steven jealous. But she winds up being chased through the hallway of her apartment building by half-naked archery enthusiast Ward Willoughby (Jack Carson). The couple agree on a divorce, but Steven then has second thoughts. On the advice of his lawyer, George Renny (Sidney Blackmer), Steven pretends he is insane, since the law prohibits Susan from divorcing him if Steven is mentally ill. Unfortunately, Susan is wise to his charade and has him committed to an asylum.
