August gave us the voice of Matt Damon in Ponyo, September gave us the inner voice of Matt Damon in The Informant!, and now October has brought us a look at his next two performances.

Clint Eastwood's Invictus is one of the last big likely contenders of the awards season, though it is as of yet unseen (unless those very few who have seen it are very good at being very quiet). Damon plays real-life rugby captain Francois Pienaar, whose team saw the support of Nelson Mandela (Morgan Freeman) as a rallying point around which they might lift the spirits of South Africa in the wake of apartheid. It's political! It's underdog! It's opening in December! It's Oscar bait for certain, and Apple has the exclusive trailer.

Paul Greengrass' Green Zone, on the other hand, was shuffled out of the Oscar race once Universal decided to sort out its slate after a lackluster summer at the box office, and that may have been a wise move. Yahoo's trailer (which is also embedded below) comes across as more of a straight-up actioner than a ready-made contender, with Damon back in Bourne mode as a betrayed soldier on the hunt first for WMDs, and then for answers. Based on the best-seller Imperial Life in the Emerald City, it opens on March 12, 2010.
