Luck would have it that I was given 10 or so rolls of 135 PolyPan F (evidently an Ilford cine film, 50 ASA with little or no anti-halation layer). Using input from fellow Caffenol experimenters on Apug and Flickr I went ahead and exposed two rolls at ISO 100, and developed in straight Caffenol-C-M, for 16 minutes at 20C. One roll agitated as usual (12 inversions first minute, 3 every top of the minute thereafter), the other agitated as usual until the 12th minute, then let stand.
Can't say I could see any difference between the two. Both were a tad over-developed. And rather grainy too. Though nothing to have a nervous breakdown over. Notice the halo effect around strong light sources, due to the lack of anti-halation layer.

I think this film has potential. These examples were rather strong in contrast, and needed a bit of work in post processing after scanning. Others have had better luck than I. Probably because they haven't pushed the film. Evidently it doesn't take to well to pushing. Next rolls will be exposed at EI 50 and developed for maybe 12 minutes. Or maybe 14 minutes, and semi-stand (agitate as normal until 8 minutes or so, then let stand - might need a spot of KBr for that - avoid streaking). We'll see.
