Asterix and Obelix vs. Caesar is a 1999 comedy fantasy adventure film directed by Claude Zidi, the first installment in the Asterix film series based on Goscinny and Uderzo's Astérix comics. The film combines plots of several Astérix stories, mostly Asterix the Gaul, Asterix and the Soothsayer, Asterix and the Goths, Asterix the Legionary and Asterix the Gladiator but jokes and references from many other albums abound, including a humorous exchange between Caesar and Brutus taken from Asterix and Cleopatra, and the villain Lucius Detritus is based on Tullius Detritus, the main antagonist of Asterix and the Roman Agent.
