The Reddit user that said J.K Simmons and Willem Dafoe were up for roles said that Imogen Potts was up for the Iris West role.
If they go with Eobard, they'll really need to find some way to differentiate from the show. Also if they use Captain Cold and Jay Garrick, does this mean they are off the Tv show like Deathstroke, Amanda Waller and Black Canary? Personally I would have loved to see Mirror Master as the first villain as he would have presented a good challenge to the Flash.
I also don't like Captain Cold's description considering he hates speedsters.
