The report of the Lincoln assassination is shown being placed on a boat in New York (to be dropped off in Ireland). Telegraph service was operating to St. John's, Newfoundland at the time, which is 1,000 miles closer to Ireland and was routinely used to put dispatches on and off ships in the manner shown in Ireland.
In the opening credits, the title is 'A Dispatch from Reuter's'. This is grammatically incorrect.
