Asterix and the Falling Sky (French: Le ciel lui tombe sur la tête, "The Sky Falls On His Head") is the thirty-third volume of the Asterix comic book series, the ninth solely written and illustrated by Albert Uderzo and the only volume to introduce science fiction elements into the otherwise historical comedy series. The book was intended as a tribute to Walt Disney and a satire on the state of the French comics industry. It was released on October 14, 2005 to commercial success, but was panned by the critics. This was the final volume produced by Uderzo before handing over the series to a new creative team. Source: Wikipedia (en)
