Bryce: On the plus side of the column, Rosie has done an enormously wonderful job for being a newcomer.

Bay: Listen, I mean, Rosie came in and she would say hello to the crew. She would acknowledge the crew. She'd say thank you.

Rosie Huntington-Whiteley (model/actor, Transformers: Dark of the Moon ): I was really grateful to everybody, from the people on the catering department to the camera boys to the producers to Shia.

Julie White (actor, Transformers series): I texted [Megan] and was like, "Come back, Lassie!" Because I think she's magic. She is the My Little Pony of Transformers.

Bay: She sent me a text three months ago. She said "I hope you're doing well." I responded, "Who is this?" She goes, "Megan, you dork!" I said, "Oh, well, thank you, hope you're well." When you're days and months on a set, it's like a family. You say rude things and you make up. Like, we were shooting a scene in front of the space shuttle and Shia called me a "cocksucker."

LaBeouf: Sometimes to make [a scene] real for me, I need to mindfuck myself. And part of that is having a speaker on set with an iPod plugged in so I can conjure emotions. And some of the songs that I like to play, Mike's not going to have it.

Bay: So Shia's gonna do his emotional scene. He gets out of his car and says, "Michael, you're gonna start with me first." And I said, "No, we're gonna start this way. This is a space shuttle! The United States of America! The last one to be launched!"

LaBeouf: So I'm playing my song and he finally says to me, "No, we're not going to play that song." And he puts on some orchestral Batman soundtrack shit. Not for me, you know?

Bay: Then he called me a "cocksucker." But I knew that he had just broken up with his girlfriend. So I didn't go after him. I just said, "That's rude. Don't call me that."

LaBeouf: It was probably the worst argument I've ever had with a co-worker—under a spaceship, screaming at him, "You motherfucker!" All this insanity. Really crazy stuff that I don't feel comfortable repeating, actually. Really gnarly.

Bay: So I ignored him for three days, and that just drives him nuts. "Mike, I'm so sorry! I'm so sorry!" I've had to do a little parenting with Shia, but he's a great kid.

LaBeouf: And then you pull your pants up and you get back to work.

In Which We Learn Our Hero Is, Okay, Yes, a Bit of a Tyrant

Johansson: He can be merciless at times, yet surprisingly sensitive.

Smith: One day he comes to our trailer and says, "Can you guys step out here for one second?" So we go, and he points up to the sky and says, "You see that big fucking orange thing? When that goes down, this scene's over. So I don't give a fuck what you say—just make sure you say it in my shot."

Bryce: He is a machine, but he recognizes that he doesn't want to be.

Lawrence: I mean, he's like the mad scientist.

Basinger: And of course, he's a screamer.

Form: The building shakes.

Smith: He's a yeller, but he's not really a fighter.

Michael Clarke Duncan (actor, Armageddon ): He's like one of those Chihuahuas that's always barking.
