Ducan Jones was also interested but after I read what he wanted to do with the character I'm glad he didn't get the job, here is what he said:
"It all worked out, though. It probably worked against me, but my pitch for a Superman film would be to take the Dr. Manhattan character from Watchmen, which I think is the best encompassing version of what Superman should be, this incredible sort of alien presence with superhuman powers who is so over powerful compared to the rest of humanity that he doesnt understand how to relate to people. And I thought thats what Superman should be, but they got Zack Snyder in there and he already knows how to do that."
