LOS ANGELES, Dec. 1 (UPI) -- Sienna Miller and Vince Vaughn star in a first trailer for Unfinished Business.
The 32-year-old actress and 44-year-old actor portray former business partners competing for the same account. Vaughn and his two associates (Tom Wilkinson and Dave Franco) must show the client a raucous good time in Europe in order to save their deal and keep it from Miller's corporate clutches.
Unfinished Business is directed by Ken Scott, with Jason Blumenthal, Anthony Katagas and Steve Tisch as producers. Nick Frost, June Diane Raphael, Ella Anderson and James Marsden co-star, and the film opens in theaters March 6, 2015.
Miller will next appear alongside Channing Tatum, Mark Ruffalo and Steve Carell in Foxcatcher. The actress is also scheduled for American Sniper with Bradley Cooper, while Vaughn is slated to star with Colin Farrell and Rachel McAdams on season two of HBO series True Detective.
