I watched the old movie 'attack' with Jack Palance, great stuff, anyone know what kind of tank it was that ran over his arm I guess it was a mock up but the running gear look familiar and I thought i spotted a m.36 in the background. :-)

It's been a while since I've seen that one, but I think that the "German" tanks were M5 Stuarts fitted with big cannon barrels.
The memory's a bit fuzzy, but I seem to recall having that impression of the film.
