Continuity mistake: After Monk has been found in the coffin, Natalie and the captain comment on his smiling and the camera shows the candle has melted down all over Monk's hand. Then when the camera comes in closer, the candle is whole again and monk's expression has changed a little from the previous shot.
Character mistake: Monk says that Croatia is a new country and didn't exist until 1992, but Croatia gained independence in 1991. However, Croatia still existed prior to that, it was just part of the Socialist Federal Republic of Yugoslavia. So things could still be made in Croatia.
