Freeman Williams’s review published on Letterboxd :
A nicely realized five-part TV documentary about the making of Winter Light, from the writing process through the premiere. Bergman was rarely this forthcoming about his process, and it makes for a fascinating watch. Seeing him rehearse his actors, just like any other director, does not provide a key to his genius, but the overall documentary reveals much about why he was - his attention to detail, his ability to see his vision through, and his love for the form.
Inspiring is not the proper word for it, but it is reassuring for anyone engaged in creative endeavors: Bergman's films were not the result of divine fire delivered from some mountaintop, but the result of his hard work and the collaboration of talented craftsmen.
