What is the most commonly used phrase in English that came from a movie?

[dtilque]

“Meanwhile back at the ranch” has to be from silent days.

I thought of suggesting that one, but then figured it originated from some book. I don’t actually know the first use; it could be either.

Googling, I find an old SDMB thread about the origin. There, @delphica reports on it being in a Zane Grey novel published in 1912.

Origin of "Meanwhile, back at the ranch"

“Meantime, back at the ranch…” is actually used to start a chapter in Zane Grey’s Riders of the Purple Sage, and this was a serial story that first ran in 1912.

Wikipedia has a page on the phrase. They say there’s no known silent movie that has the phrase as an intertitle.
