Changes from the bookEdit
The movie contains many changes from the original story:
- Dogmatix comes along with the heroes for the journey and gets a subplot involving him following the barrel thief to his house. (In the book, Obelix leaves Dogmatix behind in the village before leaving for Britain.)
- Caesar's role in the film is larger, and he has more screen time. (He had only a one-panel cameo appearance in the book.)
- Some of the characters (such as the Roman army officers and the British pubkeeper) have different names and designs. Stratocumulus is a character from the book but in the film he bears the character design of Centurion Tonsillitus from Asterix and Caesar's Gift. Governor Encyclopaedicus Britannicus of the book is replaced in the film by General Motus, who bears the name of a Roman from Asterix and the Banquet and the character design of Centurion Arteriosclerosus from Asterix and the Soothsayer.
- Asterix and Obelix meet the pirates on their way to Britain.
- In addition to the regular principal pirates, including the captain and the African lookout, there is a teenaged rookie pirate whose sole purpose in the film is to have his comrades explain their phobia of Gauls, as well as make inane comments whenever their ship is sunk (instead of the old peg-legged pirate as in the comics).
- Asterix does not get tea from Getafix, but from some Phoenicians who Obelix saved from the pirates.
- The search for the stolen barrel of potion is shorter than in the book.
- Stonehenge makes an appearance in the movie.
- In the book, Asterix found out that the barrel was sold to the rugby team by the Pubkeeper, whilst in the film the rugby team were simply the first on the list.
- During the meeting with the pirates: On the way back, the captain sank his own ship, much like in the book Asterix and Cleopatra.
- In the English dub, Fulliautomatix and Impedimenta were renamed to Blacksmix and Instantmix respectively.
- In the book, the uniform of the rugby team that had the magic potion, Camulodunum, was white and blue, identical to Colchester FC's current colours.
