Religious Allegory in Metropolis:
Freder in Metropolis is one of the more overt examples. Freder's Father, Johann Fredersen, is the overlord of Metropolis. As Metropolis stretches for miles and includes good things (such as marvelous theatres and stadiums) and bad things (a red-light district) it can be seen to represent the World. Fredersen, as both ruler and builder of Metropolis symbolized God, and Freder, his son, would therefore be Jesus. Furthermore, when Johann Fredersen asks his son what he was doing in the machine halls, he says that he wants to see the little children who are his 'brothers and sisters'. He identifies with children, even though he is in his twenties, and this could be a reference to Jesus Christ's saying 'Suffer little children to come unto me' or a sign of Freder's inherent purity. His lover is named Maria, the German for 'Mary' as in 'Mary Magdalene' and Freder is 'crucified' as he works on a horrible machine that forces him into the position of jesus on the cross.
