“Asterix in Britain” is the eighth Asterix adventure, first published in 1966, and later made into an animated movie in 1986. This is the original comic, and I really enjoy this one.
Caesar has taken over Britain, by only fighting during teatime and weekends, when the British are drinking cups of hot water and milk on their breaks from battle. All the Romans have gone over to make it part of the empire, while back in Gaul Asterix and Obelix are bored in their village. They have no legionaires to hassle, that is until a British relative of Asterix's comes and asks for their village's help. They have heard of the magic potion that gives the Gaulish village strength against the Romans, and they would like some to drive Caesar away. He gets the potion, a whole barrel, and Asterix and Obelix come with him to carry it. They dodge legions, lose the barrel, get captured, and even get caught up in a rugby match. Will the English village be able to push away the Roman armies.
It's great fun, like the Asterix's are, and shows Britain in a warm but funny and colourful way, which is interesting for a French comic. You can tell the two guys who write/illustrate the series (Rene Goscinny and Albert Udzero) love the place, and say so in the earlier prints of the comic to English fans. It's worth picking up, fan or newcomer to the series.
