Supernatural has proven time and again that it’s not afraid to try new things - with results ranging from amazing to awful and pretty much everywhere in between. Although the series shared little in common with Smallville, either tonally or storywise, both were successful CW shows with
incredibly passionate fanbases that happened to share a network. It seems only natural that plans for a crossover were at least considered.
In typical Supernatural fashion, the pitch was not what you might think. It’s wouldn’t have been the Man of Steel that the Winchesters came across, but rather the actor who portrayed him. A curse striking down former Superman actors would lead to them to search for Tom Welling in the hopes of protecting him. It’s definitely a cool idea, but one that never wound up taking shape. Would Jensen Ackles have played Jason or Dean?
