VIDEO : Tom Welling From 'Smallville' Imagined As Lex Luthor On 'Supergirl'

Fans are excited because season 4 of "'Supergirl' is going to introduce iconic Superman supervillain Lex Luthor. Reddit user BFH took the time to imagine what it would be like if Tom Welling from Smallville would like playing the role. Screenrant.com writes, "Although the fan artist uses an old photo of Welling, it isn't difficult to see the former Superman actor in that particular role, especially since a close friend and former co-star of his, Rosenbaum, could give him some pointers. This would be a great way to bring Welling back into a core DC universe."
