The two intrepid secret agents of the T.I.A. must face their most dangerous enemy: Professor Bacterium. That wouldn't be too strange, if not for the fact that Bacterium designs the T.I.A.'s most problematic inventions. The latest such device will allow any element of a movie to become real, or allow real items (and people) to become part of the movie world. But it's going to need a diamond to work.
Released in Germany in 2004 with no English translation. Released as a Spanish special edition with English subtitles in 2019 under the title Mortadelo y Filemón: Una Aventura de Cine – Edición Especial.
