Only if they're fairly cheap, about $125 or less, and the description/listing clearly states that there's no lens scratches or problems with the lens' attachment coupling. You usually don't have to worry about the auto-focus working or not, because if the listing says it isn't working, it'll likely be cheaper, and for film you won't need that functionality anyway. So beyond those, they're a pretty damn good investment for the low-budget filmmaker.
I use a Panasonic GH4 now, which is a Micro-4/3rds camera. And the cool thing about them is that any micro-4/3rds can use really old vintage C-mount screw lenses, the kind used on Bolex film cameras. Really tiny 1-2 inch lenses that fit in your palm. They make them for security cameras now, and I bought three that were designed and packaged for micro-4/3rds with an adapter right inside the box. They were small, under $50 each, fast at 1.2, 1.4, and 1.6 f-stop, and their image was a little foggy; but in a desirable, retro photograph sort of way.
Not everybody may like them, but they saved me a lot of hassle when getting the lenses I needed for my film, because they were fast and cheap. And in most cases, things don't come that way. But to me, these lenses proved fast, cheap, and good quality. So it was a done deal.
Buying used or older Nikon and Canon lenses should yield similar results, although finding used lenses with wide f-stops might be a little hard. You just have to do some research into what models of lenses can fit into modern cameras, and which ones have adapters that have been made for them. Because if not, then you'll end up with a bum lens that can't be used for anything. So just be careful about that and read descriptions and listing titles carefully.
