Eastwood stars in the drama as Gus, a wizened old talent scout for the Atlanta Brave who doesn't put much stock in fancy computer-tallyin' and, presumably, sabermetrics.  When Gus is sent on a hugely important scouting trip while he eyesight deteriorates to almost nothing, he asks his semi-estranged daughter Mickey, played by Amy Adams, to accompany him. 

As director Robert Lorenz explained a few weeks back when the first images from the film debuted online, "He gets his chance to prove whether he still has value as a scout—and as a dad. They’re having trouble communicating. They always have, and now they’ve come to a point in the relationship where it’s either going to change or it’s not. He needs a little help, and she decides it’s worth the effort.”

The trailer, which showed up at Yahoo! Movies, sticks pretty closely to a light dramatic formula, leaving out Gus's infirmity and instead setting him up as a crotchety old cuss.  It also suggests that the film might lean very heavily on baseball metaphors, but when the object of a game is to get home, you can't fault somebody for making the connections clear.

Eastwood has become a prolific director over the last decade or two, and hasn't appeared in another director's film since Wolfgang Peterson's In the Line of Fire back in 1994.  He was lured out of semi=acting-retirement by Lorenz, who has long served as either Eastwood's producer or first assistant director (sometimes both).

Lorenz managed to get a straight-up legend to star in his feature directorial debut, along with three-time Oscar nominee Adams and the ubiquitous Justin Timberlake, who plays a scout and former MLB player discovered by Gus.  The supporting cast also includes ringers such as John Goodman, Robert Patrick, and Matthew Lillard.

Trouble With the Curve arrives in theaters on September 21st.
