No, NTSC on a CRT is drawn one line at a time (it is physically scanned by the electron gun). But TV is not NTSC any more and CRTs are dead/dying.
Your HD flatscreen (plasma or LCD) does not draw one line at a time. HD is decoded into a framebuffer and that framebuffer is drawn on the screen in some hardware specific way. It may be rectangles, or the whole screen, or different vertical/horizontal slices (with very high refresh rates so you don't see flicker).
Edit: Moveover, "film" is almost always digital nowadays (I don't think I've seen a non-digital projection in the last 5 years) which means that the picture gets to the screen via some form of LCD projection. So your home TV and film are basically the same at this point. You would've been right 10 years ago, though.
