People always ask me when I started doing Twilight if I did a lot of research on being a vampire, and I say no, because Carlisle is kind of an antivampire. He never really embraced it, so for me it was more a study on humanity, why he wanted to retain his human traits, and what human traits he held on to.

(I think people forget that in addition to being a visionary, Carlisle is also a huge nerd, especially when it comes to science/medicine.)
"He’d always been intelligent, eager to learn. Now he had unlimited time before him. He studied by night, planned by day. He swam to France and […] and continued on through Europe, to the universities there. By night he studied music, science, medicine." - Edward, Twilight
Carlisle and I had to tweak the system a bit, given that most such screens responded to temperature. - Edward, Midnight Sun
“There’s a reason […] why – besides Carlisle – I’ve read the most books, studied the most sciences, become fluent in the most languages….” Edward, Breaking Dawn (meaning that Carlisle has read more books, studied more sciences, and is fluent in more languages than Edward is).
Carlisle coughed self-consciously. “You have twenty-four pairs, Jacob.” […] He looked embarrassed. “I was… curious. I took the liberty when I was treating you last June. […] I promise you that I did not mean you any harm. It’s just that… I find your species fascinating.” - Jacob, Breaking Dawn
He nodded seriously, and then his jeweled eyes glittered with interest. “It seems like we did something right with the morphine this time. Tell me, what do you remember of the transformation process? […] I want you to think – to tell me everything you remember,” Carlisle pressed excitedly.
"What happened?" Carlisle interjected. His eyes were suddenly bright, an amazed smile beginning to form on his face. It reminded me of before, when he’d wanted the details on my transformation experience. The thrill of new information. - Bella, Breaking Dawn
As a doctor I think Carlisle’s fascinated by [Renesmee], it’s like a case study that he’s never had before and so he’s definitely walking around documenting her and creating charts and trying to figure exactly what is going to happen with her. - Peter Facinelli
That was a hard time to pretend—there was so much work to be done, and I had no need of rest. How I hated to go back to my house, to hide in the dark and pretend to sleep while so many were dying.
Carlisle’s ideology is being threatened because Carlisle started this [family that] is anti-establishment. You have these vampires that are nomads, they are very animalistic, and Carlisle basically says: I’m not going to do that, I’m going to do my own thing over here.
I think he hopes that one day maybe this idea catches on and maybe one day you can have vampires and humans living together in harmony. And in this film if the Volturi wipe out his family that whole ideology is also completely wiped out.
Peter Facinelli on why this is not really just about protecting Renesmee.
Carlisle is Edward’s hero, and Edward wants to be like him.
[Edward] reveres Carlisle in an almost religious way […]
Carlisle plays the role of the father in the Cullen family, and Edward respects his opinions greatly, but Carlisle does not give Edward permission to do things. Edward is an adult with a century of wisdom under his belt. No one gives him permission to do anything.

Images relating to the deleted scene where Edward and Carlisle talk about the upcoming ~wedding night. Not on any of the DVDs or anything, sadly. In the bts footage director Bill Condon is talking to them, something about how Carlisle mentally makes a joke or otherwise thinks something to lighten the mood.
I can’t find the exact quotes, but it was something like it was Peter’s idea to add the scarves, and it was partly about having a sort of old world dignity and partly because he thought it would be interesting if Carlisle were a little bit traumatized from how he was turned and so didn’t like having his neck exposed. If you look at the first couple movies, he’s almost wearing a scarf and even when he’s not he’s usually got some sort of high, popped-up collar instead (like in the kitchen scene).
(Oh wait, found one: “I just felt like it added a little piece to his character. It wasn’t in the book but I thought it might be interesting that because he was bitten maybe he has a fear of having his neck exposed.”)
The scarves were sort of ‘laid to rest’ in Eclipse, again in a very intentional way that Peter talked about. When the wolves show up to watch the Cullens’ fight training, you noticed Carlisle is holding his scarf when he speaks to them rather than wearing it. It was symbolic of him being vulnerable and exposed. After that he didn’t really wear them anymore.
I thought Rosalie’s gloves in the first movie might have had a similar story. If you notice she’s almost always wearing them. I kept trying to come up with a good explanation of them like… maybe Rosalie is sensitive about how cold her skin is and so wears gloves so anyone she touches won’t know? But it turns out it wasn’t a character thing, just a practical thing: during filming of the kitchen scene when she broke the bowl, Nikki cut her hand. So she had to wear gloves for the rest of the shoot a) so she wouldn’t cut herself again and b) to hide the bandage.
