Factual error: The telephone for the phone bank doesn't have a phone jack cord connected into the back of the telephone. (01:15:14)
Audio problem: During Rusty's conversation with Hardy (about knowing he doesn't want to be at the orphanage), some camera views of Hardy from behind show his cheek (and therefore his mouth) making little and insufficient movement for the words he is saying. In particular, Hardy saying, "Look, you can make me play this little game of yours" and "We done here yet, coach?" didn't show adequate facial movement from a rear angled view. (00:22:30)
Factual error: At the end of the film, Hellfire Jack returns the toy soldier to the son of the late William Hawkins in 1917. Hawkins son is shown taking it upstairs and placing it in front of a photo of his father, in between two medals. These are the British War and Victory Medals - these did not exist until 1919, and in most cases were not even issued until the 1920's.
Factual error: Sassoon's Military Cross medal is shown ending up thrown in the Mersey and sinking. In his own words from "Memoirs of an Infantry Officer", published in 1930 - "I ripped the MC ribbon off my tunic and threw it into the mouth of the Mersey. Weighted with significance though this action was, it would have felt more conclusive had the ribbons been heavier. As it was, the poor little thing fell weakly on the water and floated away as though aware of its own futility."
