Mortadelo y Filemón: Una Aventura de Cine

When the two agents arrive in the horror level, they will meet a character called Dr. Ibanstein, who is an obvious Frankenstein parody. However, when you let them look at him, both Mortadelo and Filemón will state that his face seems familiar to them. And indeed: on closer examination, Ibanstein looks a lot like Francisco Ibánez - the Spanish comic-strip artist who originally created the two.
