Having already worked together on this December's awards contender "Invictus," Matt Damon and Clint Eastwood have decided to reunite on the new Warner Bros. thriller "Hereafter."

According to Variety, the project is Eastwood's first foray into the supernatural and features a storyline the studio would like to keep under wraps a la "The Sixth Sense." 

The movie was written by Peter Morgan, who received Oscar nominations for his screenplays for "The Queen" and "Frost/Nixon." Steven Spielberg is one of the film's executive producers, but DreamWorks is not involved in the production.

Eastwood rarely works with the same actor twice, so this is a high compliment to Damon from the master filmmaker.  Two notable exceptions being Morgan Freeman ("Unforgiven," "Million Dollar Baby," "Invictus") and Marcia Gay Harden ("Space Cowboys," "Mystic River").

Damon next release is "The Informant" which opens nationwide on Friday.

"Hereafter" will begin production this fall.
