Vince Vaughn’s UNFINISHED BUSINESS First Trailer and Poster The first trailer (in green plus red band version) and poster for the upcoming comedy UNFINISHED BUSINESS just arrived on-line. The movie, directed by Ken Scott (Delivery Man), stars Vince Vaughn, Tom Wilkinson, James Marsden, Nic Frost, Dave Franco, and Sienna Miller. UNFINISHED BUSINESS will be released in US theaters on March 6, 2015. A hard-working small business owner (Vince Vaughn) and his two associates (Tom Wilkinson, Dave Franco) travel to Europe to close the most important deal of their lives. But what began as a routine business trip goes off the rails in every imaginable – and unimaginable – way, including unplanned stops at a massive sex fetish event and a global economic summit.
