NEW YORK — Michael Douglas is more accustomed to playing dashing leading men and corporate types, so he took a deep breath when offered the role of an ornery widower with a second chance for love in the romantic comedy "And So It Goes." The film reunites the Oscar-winning actor with director Rob Reiner, who both worked together on the 1995 movie "American President." Douglas also stars opposite Diane Keaton for the first time in his career. "It was one of those stories that you guess you are finally ready for," Douglas said about the film that opens in US theaters on Friday and produced by Warner Bros' Castle Rock Entertainment. "I am going to be 70 in a couple of months," he added. "You really don't think you have changed that much but you have." — Reuters
