Corrected entry: At the beginning of the 1900s Coca-Cola advertised Santa as wearing red clothes to match the Cola, before that he was green, so when you see the pictures of early Santa his clothes would have been green instead of red.
Arthur Christmas (2011)
1 corrected entry
Directed by: Barry Cook, Sarah Smith
Starring: Bill Nighy, Jim Broadbent, James McAvoy, Hugh Laurie
Continuity mistake: Arthur's older brother gets "bombed" by a seagull. In the very next scene, there is nothing on his jacket, but the offending "message" appears again a little later on.
Correction: The Coca-Cola Santa advertisements began in 1931 and before that he was wearing red, too - noted in 1927 in the New York Times.
