Check out this HBO Films teaser promo reel for biopic "Hemingway & Gellhorn" (May 2012) about the tempestuous romance between war journalists Martha Gellhorn and Ernest Hemingway, directed by Phil Kaufman, yet another disenfranchised Hollywood filmmaker turning to HBO.

This movie looks expensive. Nicole Kidman and Clive Owen do the honors, with support from David Strathairn, Robert Duvall, Joan Chen, Molly Parker, Parker Posey, Rodrigo Santoro, Santiago Cabrera, Peter Coyote, Saverio Guerra, Diane Baker and Tony Shalhoub.
