Superman: The Mechanical Monsters (1941)
Superman: The Mechanical Monsters (1941) can be termed as an all time classical era of the superhero. Like always, Superman in this particular series is also out there to protect Metropolis from the many arch-rivals always trying to destroy the peace of the world.
The opening scene is the typical Superman signature style, with people shouting "Up in the sky" ,"Look, its a bird", "Its a plane", "Its Superman" accompanying this opening scene is drum-rolls and trumpets taking you to the old school of cartoon making techniques. What would really catch the viewers attention would be the way Superman is shown in the cartoon. Quite hilarious, at-least that is the case with people of 2011.
