A lot of directors look at shooting on actual film as almost a gimmick at this stage and kind of a costly one. The techs that deal in the loading/processing/storing of the media are getting more rare as the old timers retire out and there’s more things that can go wrong at every level of the use of the older medium because it’s heavy and it is more time consuming which racks up labour costs.
Camera folk work long ass hours compared to the rest of the shoot crew so it’s favours younger techs. Those who were around in the heyday of actual film have all but moved up the ladder to DOP positions or retired meaning the new blood isn’t getting the old process passed along and there’s a certain level of “fuck this shit attrition” that keeps career longevity in the industry low. The techs who specialize in film are very caught up in the romance of physical film the same way some writers use typewriters but all in all it is a dying art that fewer and fewer studios are willing to bankroll.
