Keep your insulin handy while having a look at the first trailer for Marley and Me, the screen adaptation of John Grogan's tearjerking best-seller about "live and love with the world's worst dog." Moreover, keep your eyes peeled for Owen Wilson and Jennifer Aniston, clinging to their bit-playing, beach-trotting pride as the namesake puppy's owners — helpless against its mischief, impossible cuteness and promotional star power. Look for the first teaser posters to follow shortly, with the A-listers and their names but specks below the pooch and Marley's 300-point tagline: WATCH THE DOG YEARS FLY BY. We can't wait for Christmas! [Fox via Vulture]
