Zack Snyder talked about paying homage to Smallville saying:
On the film’s ”Smallville” references (look closely for homages to the characters of Chloe and Whitney)
"Ya know, [TVs Smallville is] in the Superman mythology now. I was interested in that kind of homage to the mythology. I feel it’s not so much about paying more homage to the series, it’s just in the vernacular of Superman now."
