Continuity: When Juliet first sucks a bullet out of Rigby, she wipes off her lipstick first. After sucking out the bullet, she's wearing lipstick again although she never reapplied any.
Anachronisms: When Rigby is talking on Juliet's phone to her sister Leona, the handset and coiled cord to the phone are from the 1960's-80's, and not the straight cloth-covered phone cords in use in the 1940's when the story is taking place.
Anachronisms: Rolodex card file wasn't marketed until 1958, yet appears on a desk in scene set in Forties.
Anachronisms: Panty hose, introduced in Sixties, appear in a scene taking place in mid 1940s.
Anachronisms: At one point Reardon references the Kinsey Report; the first volume was published in 1948, but the movie is set in 1946.
Revealing mistakes: When Juliet sucks the bullet out of Rigby, we are shown her mouth with the bullet between her teeth, the base of the bullet facing us. But the bullet is backwards. Since a bullet would enter an arm nose (rounded end) first, that is the end we should see if it was just removed.
