You may not need 'film' - you can get 'pin hole' adapters to fit popular DSLR's - see what you've taken without the risk of 'wasted' film !!! (may not be in the spirit of 'pin-hole' photography though ! ! ! )

Several of the cameras take roll 120 or 35mm film as far as I am aware.
I used cut paper film many years ago and that is still available according
to some of the ads.

If you have the time and the inclination, you can have a lot of fun experimenting with pinhole cameras. All you really need is a box with a bit of tinfoil on the front and some grease proof paper on the back. Stick a fine needle through the foil, and see the image formed on the grease proof paper. For film, you can make your own blueprint paper, which you can process in daylight. OK, it's a bit more complicated than this, but it really is very easy and very rewarding.
