It’s an early holiday gift from Sin City. CBS Films and Good Universe’s Last Vegas will be hitting theatres on December 20, 2013. The comedy about four friends who throw a bachelor party in Las Vegas for the last of the gang to remain single packs a lot of seasoned star power. Michael Douglas and Robert DeNiro star, with the former playing the remaining bachelor among the pals. Kevin Kline is also in the cast and Morgan Freeman stars as well. The guys are joined by Mary Steenburgen as a lounge singing love interest for both Douglas and DeNiro’s characters. Jon Turteltaub directs from an original screenplay by Dan Fogelman. Laurence Mark and Amy Baer are producing, with Good Universe’s Nathan Kahane executive producing. Matt Leonetti will co-produce. Filming is set to start later this month in Atlanta and Las Vegas.
