John Jackson, "Downsizing"

MEET THE MAKER CASTING ENSEMBLES HAS BECOME SOMEWHAT OF a specialty for John Jackson, the man behind fleshing out Paramount Pictures' "Downsizing."For Alexander Payne's first foray into science fiction, Jackson joined the two-time Oscarwinning writer-director in assembling a roster of movie stars for roles big and small to share the screen with little-known international talent pulled from markets like Canada, Scandinavia, Serbia, and Vietnam.The near-future dramedy follows Matt Damon as Paul, who chooses to "downsize" (physically shrink to five inches) himself, his wife, Audrey (Kristen Wiig), and his children in an effort to fix the world's overpopulation crisis.
