Of all the comic book artists, Frank Miller is one of the most famous in the world. He originally drew and wrote the Daredevil comics for Marvel comics, but he has gained renown as the creator of the Dark Knight Returns. He is not old enough to claim the fame of having created Spiderman, but in his career as a professional comic artist, he has worked with many major comic publishers such as Gold key, DC Comics and Marvel Comics. He did write the two issue story of the 'Spectacular Spiderman' and was the original penciller of the Daredevil series.
Frank Miller is the comic book artist that developed the character of Electra, the female Ninja assassin. He even worked on the film when the comic book was made into a movie in 2003. Apart from his work with comic book publishers, Miller has gained international recognition for his own works, which include Ronin, (a science fiction samurai action story) that he worked on with his wife, Lynn. Sin City is his own creation, which is a series of crime stories in black and white pictures. The Dark Knight Returns is a futuristic tale of Batman in which the superhero is a violent vigilante. The Dark Horse comics are based on the screenplays he wrote entitled RoboCop.
Many comic book artists start off drawing comics as children and progress through art school where they learn the proper techniques of shading and coloring. Formal writing training is also necessary for those who want to write their own comic scripts and storylines. You also need to gain experience through internships and apprenticeships if you hope to get hired by one of the comic book publishers.
Comic book artists often make a living by creating online cartoons or start creating their own comics that they self publish and market themselves. Often the better comics that are created in this way are often picked up by one of the major companies.
