For Disney fans, it is hard to believe that “Frozen” (2013) was released just six years ago. The tale, inspired by Hans Christian Anderson’s “The Snow Queen,” has permeated pop culture in a way that even Walt Disney Pictures couldn’t have predicted when it was released. Directed by Chris Buck and Jennifer Lee, “Frozen”’s themes of family, love, isolation, and finding yourself have resonated with people across the globe. And of course, “Let It Go” became such a hit that it was almost impossible to avoid hearing it for many months. In addition to the film making it onto In Their Own League’s Top 50 Female Directed of the Decade list, now is an appropriate time to look back at the first “Frozen” film as its sequel has just been released.
