Some video copies omits Jean Servais scenes as a Free French admiral making a short speech to his crew before the shore bombardments starts.
Some video copies omit Jeffrey Hunter's "dear John discussion" with a fellow soldier abourd a troop transport. Jean Servais' part as a French admiral giving a speech about firing upon one's homeland was cut out too.
Some video copies add a close up of the Spitfire pilot who attacks the German troop column late in the film.
The version that was shown on Swedish TV in the early 90's lacked any original subtitling (e.g "Generalfedtmarshall Gerd von Rundstedt, OB West") whatsoever including the film's title!
There is a digitally remastered colorized version of the film.
There are two distinct versions of this film: in one, all the characters speak English; in the other, the French and German characters speak their own respective languages, with subtitles. In the latter version the theme played over the end titles is an instrumental, while the former has lyrics written by Paul Anka (the latest DVD version contains both the German/French speaking and the vocal version of the film's musical theme).
