Factual error: Captain Stanley says of Australia "What fresh Hell is this?" The scene takes place in the 1880s, yet the quote is attributed to Dorothy Parker, who would not have been born yet.
Other mistake: Captain Stanley takes the lid off a small bottle on his right and puts the lid on the desk. He pours a drink and the lid miraculously appears in his left hand. He then screws it on the bottle. Screw top bottles weren't around till 1920. (00:54:50)
