Edouard Baer (who plays Astérix in this film) has previously appeared in Asterix e Obelix: Missão Cleópatra (2002), as Otis.
Based on René Goscinny and Albert Uderzo's "Asterix in Britain" and "Asterix and the Normans", both published in 1966.
Pindépis (Atmen Kelif) is referenced to as a 'sans-papyrus'. This is a play on the French term 'sans-papiers' (lit.: 'no papers') for an illegal immigrant.
The sentences that are told to a girl in one of the first scene of the movie by Goudourix to a woman are from a song by Jacques Brel entitled "Ne me quitte pas" -"Do not leave me"- a very famous french song: "Où l'amour sera loi, où l'amour sera roi" -"Where love will be the law, where love will be the king"-.
