"Field of Dreams" was released on April 21, 1989, and star Kevin Costner will celebrate the film's 25th anniversary in style. Appearing on HuffPost Live on Thursday, Costner revealed that he's going back to Dyersville, Iowa, the location of the film's iconic cornfield, to mark the occasion. "I knew the movie was great. What I didn't know was that it would be as popular as it has been. That was my hope, but you don't know that about movies," Costner said.
