This look is largely achieved now in digital post-production. With film, it's hit-or-miss with no combination of film, processing or gear assuring immediate, consistent results. Jonathan Leder is getting this and other vintage looks with film--purportedly with no digital processing--at Jacques magazine. I'd try current films with chalky, dialed down saturation and contrast like Fuji 400H and rate it at ISO100 for starters or just over-expose the bejessus out of it. I had some luck with Kodak's now-departed E200 slide film which was almost pallid compared to other Ektachrome materials. I'd avoid consumer C41 films which tend toward ramped-up saturation and contrast. It'll be a fishing trip but worth it if you can nail a few.
