Here’s the decidedly NSFW redband trailer for the international comedy starring Vince Vaughn. A relentless businessman with his own company, he heads to Germany with his only two employees (Tom Wilkinson and Dave Franco) to clinch a make-or-break deal. Complications arise. Sienna Miller and James Marsden also star in Unfinished Business, from director Ken Scott — who helmed Vaughn in last year’s Delivery Man — and scribe Steve Conrad. Fox opens it wide March 6.
