Thrilling and wildly funny, the "Tintin" stories chronicle the escapades of a junior reporter who has a nose for a good story and a talent for attracting trouble, which more often than not imperils his life! In the original Hergé comics, "Prisoners of the Sun" is the second book of a two-part story that follows "The Seven Crystal Balls." It is almost certain that the script will include both parts, retaining the title of the latter. (Much like the first film, which adapts both Hergé's "The Secret of the Unicorn" and "Red Rackham's Treasure," using the title of the former). "The Seven Crystal Balls" was originally published in 1943 as a serialized newspaper adventure. The storyline has Tintin and his friends embarking on an adventure to Peru after a mysterious illness is found to be connected with a Mummy's curse.
