The rumor that Barry accidentally crosses over to an alternate universe, and runs into someone there who's also pretty fast? A guy in red and blue...PLAYED BY TOM WELLING?
Ooops! Looks like someone posted about it below.
Quote:1. Given Tom Welling's reluctance to even put on the Superman suit, I highly doubt this will come to pass.
I kind of get the feeling somewhere in Welling's Smallville contract it said he was never to wear the costume.
Quote:2. Geoff Johns himself is on record stating that Superman, or Batman, will never appear on Arrow or the Flash.
Yes but at the time Smalleville was on, the rights battles for Superman were a bit heated compared to how it is now.
Things may have changed to allow Superman on TV.
Rather he wasn't on TV though, save him for the big screen events
