Trumbo? Yes. Douglas? No

I'm a big fan of Dalton Trumbo, a writer who fought the good fight when that was difficult to do. And, judging from this trailer, it seems Bryan Cranston has nailed the part. But see if, like me, you feel something jarringly wrong here.

From the small snippet I saw in this trailer, the actor, Dean O'Gorman, who is supposed to be playing Kirk Douglas neither looks nor sounds anything like Douglas. I'm just hoping it's not too late to fix this. The look can be fixed cosmetically: correcting the hair style and color and finding a way to put a hole in O'Gorman's chin. Then, perhaps, you can recruit someone like Frank Caliendo to dub the audio. Where's Frank Gorshin when we need him?
