Except that Charles is right. Circles of Confusion are, in reality, 3-D volumes, wherein the point of focus is differing by the wavelength of the light. So, the point of perfect focus shifts from front to back in the space of angstroms, well withing the emulsion depth of halide on acetate.

But isn't that what Bob's saying? That focus is more critical on video? He said with video the nose is in focus and the eyelashes are softer and the film is more forgiving.

Yes,
that's what I'm saying. In all fairness though the best film stocks I'm told can deliver 4K resolution. You do not see anything like that in a release print though, more around 700 lines according to SMPTE's tests.
I wouldn't say though this is a film Vs video argument. I think you'll notice a difference in DOF between a PD170 and a Z1.
