Can Canon EF and EF-S lenses be used on EOS film cameras?

I have a Canon EOS 500D with a mix of EF and EF-S lenses, and I’m thinking about buying an inexpensive Canon EOS film SLR. Since the mount looks the same, will my current lenses work on an EOS film body? In particular, are EF-S lenses compatible, or only EF lenses?

All your EF lenses will work. EF-S lenses however will not as they protrude into the body of the camera a little more. They are designed for the smaller sensors (and therefore smaller mirrors) of APS-C digital SLR's, where the smaller mirror flipping up still clears the flange of the lens. A 35mm film SLR (or indeed full frame digital) has a larger mirror which will hit the rear of the lens as it actuates, and will most likely break/damage the camera.
DO NOT USE EF-S LENSES ON A FILM SLR
Regular EF lenses are fine ;-)

Canon EF lenses are compatible with EOS film cameras. Canon EF-S lenses are generally not.
EF-S lenses are designed for APS-C digital bodies and extend farther into the camera. On a 35mm EOS film SLR, the larger mirror can strike the rear of the lens, which risks damaging the camera or lens. Canon also added a physical mount difference to prevent EF-S lenses from being mounted normally on full-frame/film EOS bodies.
Even if an EF-S lens is modified to fit, it may vignette heavily because it was designed for a smaller image circle. Any apparent usability can depend on the specific lens and focal length, but it is not considered safe or proper compatibility.
So the practical answer is:
- EF lenses: yes
- EF-S lenses: no, do not use them on EOS film SLRs
