Hollywood North has shared some photos from the Vancouver set of The Flash, and as you can see by following the link in the Tweet below, they offer up a first look at a pretty massive actor wearing a motion capture costume for what the site believes will be the villainous Savitar. Unfortunately, it appears as if Iris West is going to be caught in the crossfire between him and the Fastest Man Alive!
It makes sense that this is Savitar, especially as his comic book counterpart is also pretty huge. Why he's being brought to life with special effects remains to be seen, but in a new interview with Entertainment Weekly, executive producer Greg Berlanti confirms that we'll see him appear in episodes six and seven. That means we won't have long to wait until finding out what he looks like.
In the same chat, he also reveals that the secret identity of Dr. Alchemy will be revealed in the midseason finale. Who do you think is beneath the mask? Up until recently, I would have placed my money on Julian Dorn, but it's hard to say. It's clearly going to be a big moment anyway, hence why it's being saved for this episode (leaving us to wait until next year for it to be followed up on).
