I well remember back in the 1970s that the New York Film Festival had a mini-festival of films that had recently been found and restored; they included Jeanne Eagles' "The Letter," Raoul Walsh's "Regeneration," Frank Borzage's "Liliom," and this film. Since it was a film made by Murnau, there was immediate interest.
Thankfully, all of the films listed have been released on DVD and are all worth seeing. "City Girl" is a beautiful film despite it's flaws, which were not Murnau's fault. As is known, the studio demanded that sound sequences be added to the film, and took final cut away from him. The silent version of this film seems to be the only one still available, and comes the closest to what he originally wanted.
The Masters of Cinema series similarly issued a Blu-ray of Murnau's "Sunrise." Both were licensed from 20th Century-Fox and were issued in a big DVD box here in the U.S. But Blu-ray makes the difference; both films are luminous. You don't get much better than this given the source material and the age. And even better: they are region-free, so they play on my Blu-ray player which is region 1.
If you love silent films, "City Girl" belongs in your collection. I recommend it without hesitation.
