Nolan’s sci-fi adds four more.

Multiple outlets are reporting that Oscar-winning veteran actress Ellen Burstyn, rising star Mackenzie Foy (‘The Twilight Saga’), Bill Irwin (‘Higher Ground’), and Timothee Chalamet (‘Homeland’) are set to join the cast of Christopher Nolan’s upcoming sci-fi movie ‘Interstellar.’

Based on the theories of physicist Kip Thorne, the sci-fi follows a group of explorers who travel through a wormhole and into an alternate dimension.

Nolan’s impressive cast already includes the likes of Matthew McConaughey (‘The Wolf of Wall Street’), Anne Hathaway (‘Les Misérables’), Jessica Chastain (‘Zero Dark Thirty’), Michael Caine (‘Now You See Me’) and Casey Affleck (‘Out of the Furnace’).
