As we've started to get our fair share of trailers for the coming prestige projects -- Frost/Nixon, The Soloist, Zack and Miri Make a Porno -- I was curious as to why we'd yet to get one for Clint Eastwood's period drama, Changeling, if it were set to open by the end of next month. Particularly after Kim's Cannes review, I wanted to get a proper glimpse beyond a brief clip...

Perhaps hearing my prayers or just tiring of my complaints, Yahoo! Movies saw fit to post the trailer (watch it after the jump as well), in which a young mother (Angelina Jolie) in 1928 Los Angeles finds herself standing up against a corrupt police department when her missing son is returned, or rather replaced by a different child altogether.

Even if the same piece of score hadn't been used in both of their trailers, I'd still have felt a need to draw a correlation between this and last October's missing-kids-and-corrupt-cops powerhouse, Gone Baby Gone (of course, it doesn't hurt that Amy Ryan shows up in both of them). From Eastwood's end comes a particular tinge of Mystic River, and so far as I'm concerned, all of those signs point to something substantial waiting for us when Changeling opens in limited release on October 31.
