Wachowskis are the Matrix folks and Tykwer is known for Run, Lola Run. (http://www.imdb.com/title/tt0130827/ worth watching)  Each of the three directed different segments of the film which uses the same actors/actresses in different time periods as part of a larger story.

For me the cast is going to pull me out of the story.  Unfortunate, but I guess they felt they needed a narrow casting net to get attention.

The three directors explain the project in a video here: http://www.cinemablend.com/new/Watch-Wachowskis-Tom-Tykwer-Explain-How-Cloud-Atlas-Got-Made-32133.html
