About KryptonSite
In a time before social media, Craig Byrne created KryptonSite as the ultimate fan destination for The WB/CW series Smallville which starred Tom Welling, Michael Rosenbaum, Kristin Kreuk, Erica Durance and more. In the decades since, KryptonSite has grown to cover newer Superman-related TV and movie projects while still always holding on to Smallville.
