Another actor has joined Christopher Nolan's next directorial effort, "Interstellar."  Matthew McConaughey, Anne Hathaway, Michael Caine and Jessica Chastain are already on board. Now the movie, with no announced plot, has also snagged former "That 70s Show" star Topher Grace, ComingSoon reports.

The role that Grace is playing hasn't been disclosed. The movie is said to involve time travel and an interstellar voyage, hence the name.

Nolan wrote the script with his brother, Jonathan Nolan and will produce with his wife Emma Thomas and Lynda Obst. It's still a long way off, with a release date currently scheduled for November 7, 2014.
