Double indemnity directed by Billy Wilder (1944)

Its based on a married Queens woman and her lover. Ruth persuaded her boyfriend, Judd, to kill her husband Albert after having her husband take out a big insurance policy—with a double-indemnity clause. This film uses the use of real time and remembered time. Using effects like flashbacks which is narrated by a voice over occasionally, so you can understand the story line, so when it comes back into the present you know another fact of the underlying story.
