Despite playing The Flash to much critical acclaim on TV, Grant Gustin won't be the Scarlet Speedster in the DC Films universe -- and viewers aren't the only ones disappointed. According to Gustin's "The Flash" co-star Tom Cavanagh, not casting the actor as the movie universe's Barry Allen is a big missed opportunity.

Speaking to Nerdist, Cavangh criticized Zack Snyder's comments on DCTV, in addition to suggesting that Gustin would've made a good movie Flash.

The Harrison Wells actor told the site, "It was either Variety or Vanity Fair that wrote an article that said [DC] needs to watch what they're doing on TV, because the TV's working and some of the other darker stuff isn't working. Here's what I'll say about him not being The Flash. The first thing is that for Zack Snyder to say 'that's not really the universe that we're building,' it's excruciating for an actor. Because you're like, 'Uh, what about acting?' He's a clean-cut guy and winning, yes, because he's acting that. He's not Barry Allen. He's Grant Gustin. He created that thing. If you want [your Flash] to have long hair and be a slacker, believe me, Grant can play that."

Cavanagh continued, "[Gustin] makes it look easy and makes everyone think that's what he is because he's an incredibly skilled talent. That's why he has that job. That's why people like the show. If Zack Snyder were to read him for [The Flash], he would be shocked. It's crazy for a big-time Hollywood director to say 'that's not the universe.' It's a huge misstep on his part. If you're a director, and you're worth your oats, then you should be able to, given an actor with talent, mold him into what you want, and Grant could do that."

Revealing what he said to Gustin at the time of the "Flash" movie announcement, Cavanagh said, "I said to Grant when [the "Flash" movie] was announced: 'Look, that's years from now. Do you just want to just be The Flash? You have the ability to be in a Spielberg war movie next.' And that will happen for him. For his first big movie role to be The Flash, I don't know if that's the best thing for him. because you're asking him to do the same thing he's had years to do, to do the exact same thing in two hours, and it's in different hands creatively. It's tricky."

"The Flash" returns this fall, Tuesdays at 8/7c, on The CW.
