For his next film "Interstellar," director Christopher Nolan has done a masterful job of keeping anything of great detail out of the press. The current plotline - and one that could serve as the basis for any run-of-the-mill scifi film - reveals only this: 

"A group of explorers make use of a newly discovered wormhole to surpass the limitations on human space travel and conquer the vast distances involved in an interstellar voyage."

The film features a stellar cast including Matthew McConaughey, Anne Hathaway, Jessica Chastain, Matt Damon, Bill Irwin, John Lithgow, Casey Affleck, David Gyasi, Wes Bentley, Mackenzie Foy, Timothée Chalamet, Topher Grace, David Oyelowo, Ellen Burstyn, and Michael Caine.

Up until today, we had no idea why such an interstellar voyage might be necessary - but thanks to the Fort Macleod Gazette, we may have our first clue. The town, located in Alberta, Canada, was the site of filming this week. 

"Set in the future, the movie details the toll climate change has taken on agriculture, with corn the last crop to be cultivated," Frank McTighe writes. "The scientists embark on a journey through a worm hole into other dimensions in search of somewhere other crops can be grown."

According to the Gazette, a scene shot Wednesday showed McConaughey driving a truck through a severe dust storm - which would seem to back the whole ruined Earth idea. 

Look for "Interstellar" to bow sometime in 2014.
