It's a new dawn for the "Teenage Mutant Ninja Turtles," but not everyone is ready to join in on the pizza party just yet.

The heroes in a half-shell are returning to the big-screen in 2014 with "Ninja Turtles," directed by Jonathan Liebesman and produced by Michael Bay. Yes, the Michael Bay — the same man behind "Transformers," a highly lucrative series of films, but one that many longtime fans of the franchise didn't embrace. Bay's involvement in yet another beloved geek-friendly property has left several "Turtles" loyalists worried about the "Bayhem" to come.

But one of the stars of "Ninja Turtles" — Alan Ritchson, who plays cool but rude Raphael — says the director's detractors are in for a shock.

"People think they know what this movie is about," he told MTV News on the red carpet of the MTV Movie Awards on Sunday. "But they have no idea. It's going to blow people away, guaranteed."

Ritchson said he relates to fans who grew up with the "Turtles" toys, cartoons and comics. "I grew up with it, too! When I heard about it, I was like, 'Oh, I don't know. Do I really want this? It's Michael Bay. He tends to be more popcorn than a lot of people like,'" he admitted. "But as soon as I saw the renderings they have for these characters, I knew how sick this was going to be."

"It's going to be huge," he said.

For Bay, "Ninja Turtles" isn't just another adaptation. It's also a reunion with his original "Transformers" leading lady, Megan Fox, who stars in "Turtles" as intrepid reporter April O'Neil. Bay and Fox famously feuded in the aftermath of "Transformers: Revenge of the Fallen," leading to Fox's exit from the series. But Bay recently told MTV News that reports of their conflict were greatly exaggerated.

"The press made it a lot bigger than it ever was," said the director. "The other day, [Fox] hugged me and called me a 'Jaguar.' What the heck does that even mean?"

Perhaps we'll find out when "Ninja Turtles" storms theaters on June 6, 2014.
