Today unveiled it Thursday morning, before it went immediately crazy on the Web.
And Dakota Johnson and Jamie Dornan were on the show to talk – briefly – about it.
"What was it like to shoot explicit scenes, to be naked all day?" asked Savannah Guthrie.
Johnson: "It's not like a romantic situation. It's more technical and choreographed. It's like more of a task."
Dornan: "We got ourselves into situations that are not that natural and not that easy, so there had to be trust."
Savannah asked them after it aired: Is that a good example of what we can expect?
"Yeah," said Johnson.
