Directors Andy Wachowski and Lana Wachowski are currently shooting the adaptation Cloud Atlas, and it seems they already have their follow-up planned with the Warner Bros. project Jupiter Ascending.

The story line is being kept under tight wraps, but the project is said to bring Andy Wachowski and Lana Wachowski back to their sci-fi roots. The Wachowski's came up with the original idea and will write the screenplay.

The directors and studio are currently mulling over which A-list actor to pitch the project to. It isn't known when Cloud Atlas will wrap production, although it is said Jupiter Ascending is being targeted to start production as early as spring 2012.

It is also said that Andy Wachowski and Lana Wachowski's Cobalt Neutral 9 isn't moving forward, since they couldn't secure financing. The story centers on the relationship between a gay U.S. soldier and an Iraqi citizen.
