Some recent trailers of a political bent: Sen. Tom Cruise urges stay the course, journalist Meryl Streep harbors doubts, and guidance counselor Robert Redford soapboxes like it’s going out of style in the full trailer for Redford’s Lions for Lambs, also with Peter Berg, Derek Luke, and Michael Pena. Or, if you take your Meryl dark, Reese Witherspoon’s Arabic husband falls awry in the CIA secret prison system (or does he?) in the more compelling trailer for Rendition, also with Streep, Jake Gyllenhaal, Peter Sarsgaard, Alan Arkin, J.K. Simmons, and Omar Metwally. Elsewhere, an Afghani emigre (Khalid Abdalla) ventures home, into the realm of the Taliban, to honor the last wish of a childhood friend in Marc Forster’s version of Khaled Hosseini’s The Kite Runner. And, for more historically-minded muckraking, Ed Harris, Helen Mirren, Harvey Keitel, and Bruce Greenwood join alums Nicolas Cage, Diane Kruger, Jon Voight, and Justin Bartha in unlocking the hidden mysteries of the presidency in the trailer for National Treasure 2: Book of Secrets. (A totally cheesy b-movie, to be sure, but I enjoyed the first one more than the ponderous Da Vinci Code.)
