Does a title need to be in italics when mentioned in dialogue?

Most style manuals will tell you to italicize the title of a book or a motion picture in text or notes—but what about dialogue? Should a title also be italicized when a character mentions it?

Yes.

Examples:

“We’re going to see the latest Star Wars flick. Would you like to come?”

* * *

“You remind me of that character Meg Ryan played in When Harry Met Sally,” Steve said.

“You mean Sally?”

Steve nodded.

“You think I fake orgasms?”

“No, I think you’re high maintenance!”

* * *

“Let’s go get something to eat.”

“Can’t. I’m on a roll.”

“You’ve been working on that every weekend for the past two months. What are you writing, War and Peace?”

“No, The Great Catsby.”
