Continuity: After Lady Bellaston reads Tom's letter proposing marriage, she wads it into a small ball, clearly wrinkling it. In the next scene, Lady Bellaston shows the letter to Sophie's aunt, but now it is smooth and uncrumpled.
Anachronisms: In the hunt scene, you can clearly see that the riders are following on a path made by automobiles. The path has tire tracks all along.
Anachronisms: As the hunt begins, we see the riders on horseback on their way out to the hunting grounds, with a tall block tower appearing in the background. Clearly visible on top of the block tower is at least one very tall radio antenna.
Anachronisms: In the scene where Tom Jones and Sophie Western are riding around on various horses within a barnyard area, one of the barn sheds in the background has an area of its roof repaired with corrugated iron. The story was set in the mid-1700s but corrugated iron wasn't invented until the 1820s.
