While doing press for Pain & Gain, director Michael Bay offered a few updates for Ninja Turtles and Transformers 4. When asked about the controversial alien origin, the filmmaker clarified that aspect of the film.

"There was that quote saying that we're making [the Ninja Turtles as] aliens. We're not. It's the ooze! It's from the original source material. These are from the original writers, and I never went out to correct myself in the press. I do listen to the fans and I do want this to be authentic. I think they're going to be really happy with this movie. When I see the digital stuff, the turtles look great."

In regards to Transformers 4, Michael Bay revealed that the Autobots and Decepticons have been redesigned.

"You know there are a couple of historians of Transformers. I would do my designs of the robots and they're like, "What if you just add a little bit more ears to Optimus?" But they're really hands off. We've redesigned them in Transformers 4, and there's some really cool sh*t in it. I'm literally redesigning every character, top to bottom. There's a reason why they're redesigned, but it's also to keep it new and fresh to me. I think the fans will appreciate some of this new stuff we have in the movie and some of the new characters."

Ninja Turtles is currently in production, with Transformers 4 scheduled to begin shooting this June.
