The obvious explanation for how Jupiter Ascending got made:

[phone rings]
Mrs. Wachowski: Lana, it’s Mom.
Lana Wachowski: Uh, hi Mom.
MW: Lana, listen, your dad and I were cleaning out the basement and we found all the handwritten screenplays you wrote in 8th grade.
LW: Um…ok?
MW: So I was reading them, and there’s this one about a space princess who falls in love with a rollerskating wolf soldier…
LW: OMG.
MW: …and anyway, I was thinking, y’know maybe this would be a good movie for you and Andy to make. Cause, to be honest, sweetie, I never understood that Matrix movie. Like, why is he bending the spoon? It’s a perfectly good spoon. It seems wasteful. And that Keanu—
LW: Mom, I am not making the space princess story I wrote in middle school into a movie.
MW: I mean, fine, all right; if you and Andy have other plans, you have other plans. I just thought it might be nice. Something different after Cloud Compass.
LW: It was Cloud ATLAS, Mom.
MW: Well, if you did the space princess movie, she wouldn’t even need a compass. Because it’s in space, and you can go up or down or—
LW: Okay, okay, fine; I will talk to Andy about making the space princess movie.
MW: Oh, well only if you want to. Oh, and Lana?
LW: What Mom?
MW: Think about casting that nice boy from Magic Mike as the rollerskating wolf soldier. Channing Whats-His-Name. The one with the neck.
LW: …
MW: …
LW: Ok, Mom. Channing Tatum as the wolf soldier. Got it. I’ll go and—wait, Mom, Andy’s calling me on the other line. Hold on. Hey, Andy.
Andy Wachowski: Hey, uh…what’s up with this space princess screenplay?
LW: Whoa, wait, how do you already know about it?
AW: Mom just faxed it to me with a picture of Channing Tatum.
