Not true. You can easily run 1000 ft of 35mm film (about 9-10 minutes) 
through a camera
at normal frame rates. (0-120fps) Older cameras like the Mitchell need 
a few
drops of lubrication every 10,000 ft or so, but that is just to avoid 
wear and tear. My
Mitchell-NCR is 70 years old and still runs like a charm.

Ultra-high speed cameras like a Photo Sonics can shoot up 360 fps. An 
example of their
use would be some of the ultra-slowmotion shots in the Matrix films. I 
haven't dealt with
these personally, and I would guess that the transport movement is kept 
well lubricated.
But I have never heard of a heat problem.
