Producer Michael Bay recently delayed the release of the Teenage Mutant Ninja Turtles reboot to 2014 as work continues on the script.
Eastman has now offered an update to NBC Chicago, revealing that he still has high hopes for the movie.
"All the intentions are in the right place. I couldn't be happier to be a part of it. I think it's going to be a fantastic film," Eastman explained.
He went on to suggest Bay's movie will be quite different to the Teenage Mutant Ninja Turtles' previous big-screen iterations.
"[Director] Jonathan Liebesman is going to make a great film. From what I've seen of the script, it's fantastic," Eastman revealed.
"Michael Bay has made some great and intense movies. We're talking about being inspired by movies like The Avengers for scope and roots origin and The Raid: Redemption for fight scenes and Rise of the [Planet of] the Apes as far as computer-quality style."
