While praising Williams's performance as Marilyn Monroe in "My Week With Marilyn," Firth mentioned the 1997 film "A Thousand Acres," where he joked that the young star was a mentor to him onset.
Despite being a critical and financial disappointment -- the film grossed just $7.9 million upon release in September of 1997 -- "A Thousand Acres" featured a highly decorated cast of well-respected actors. In addition to Firth and a young Williams, the adaptation of Jane Smiley's book starred Jessica Lange, Michelle Pfeiffer, Jennifer Jason Leigh, Jason Robards, and an even younger Elisabeth Moss (the future Peggy Olsen played Williams's onscreen sister).
