Perhaps the greatest of all film noir offerings from Hollywood, Billy Wilder's 1944 masterpiece Double Indemnity will be screened tonight as part of the Main Library's tribute to actress Barbara Stanwyck. Nominated for seven Academy Awards (including Best Picture), this features superlative performances by Stanwyck, Fred MacMurray and Edward G. Robinson as three folks involved in a murder-and-insurance scam. The screening is at 7 p.m. at ImaginOn. Admission is free.
