Sin City: A Dame to Kill For (2014)

Plot hole: Towards the end of the "The Hard Goodbye" segment from the first film after Marv has killed Cardinal Roark, a newspaper clipping shows that the Cardinal's brother Senator Roark was decrying the atrocity. However, at the very end of this movie, Nancy kills Senator Roark with Marv's assistance. Since Marv was captured and imprisoned immediately after he killed Cardinal Roark, that means that the killing of Senator Roark had to have occurred before "The Hard Goodbye", which means Senator Roark should not have been alive to decry his own brother's murder.

Dwight McCarthy: Nobody's killing anybody. Not while I'm around.

Trivia: A sequel to "Sin City" was planned shortly after the release of the original film in 2005, but due to scheduling conflicts, false starts and problems finding funding, the movie was not made until 2014- nine years after the original film came out.
