A Majority of One

When Eddie is repairing Mrs. Jacoby's TV, rather than actually shooting the scene with material already selected and pre-recorded to be seen on the TV's screen, the filmmakers used another, less expensive trick; since TV scan rates are not the same as film, whenever a TV is seen (and it's showing something being broadcast), the dark scan lines are visible (and sometimes the TV's picture will "roll"). As this was still early in the TV-era, showing TVs broadcasting was something of a novelty, but it came with the aforementioned problems. To combat this, a "TV" was built (or, more accurately, something which looked like a TV). What's being shown on the "screen"' is actually film, which is being projected from behind the scene, and with the aid of a mirror, and a semi-translucent material to give the illusion of a screen, the result is that a high-quality image is seen, and there's no problem synching camera with TV.
