Earth-1 And Earth-2 Collide

This is James Gunn, director of 2014's Guardians Of The Galaxy.

This is actor Tom Cavanagh, who currently plays Dr. Harrison Wells on The Flash.

Look at 'em! I pretty sure they're the same person. Gunn apparently uses a stage name when he auditions for acting gigs in his spare time.

Either that, or Tom Cavanagh is the Earth-2 version of James Gunn!
