Like the cosmos that Chris Nolan will be exploring in his upcoming sci-fi epic Interstellar, his cast list also seems to be ever expanding and endlessly intriguing.

You can now add Casey Affleck to that growing and eclectic list. No details yet on what role he’ll play in the 2014 mind bending time travel IMAX extravaganza, but that’s no surprise given the whole project is being kept tightly under wraps.

With Affleck Jr joining Matthew McConaughey (whom, on the basis of the Wolf of Wall Street trailer, just keeps getting better and better), Anne Hathaway, Jessica Chastain and Michael Caine, it seems like Nolan is slowly accumulating a cast to match the anticipated visual scale of Interstellar.

We’ll bring you more news as we get it.
