The legend of Saint Christopher quite clearly states that he
was a giant. Not just a tall man, but a genuine giant of the beanstalk variety.
As the story goes, it was his size that enabled him to easily
transport the Christ child across a river and thereby secured
his place as patron saint of travelers — that is, until the Church
decided that the evidence for Christopher's very existence was entirely
legendary and decanonized him. Nonetheless, Christopher remains
a popular though unofficial saint, and his image is fixed in our
cultural psyche.
Christopher's story seemed the ideal vehicle to feature another
famous giant — the late Andre Rousimoff, professional wrestler and actor (which amounts to the same thing).
