First credited film role for Lynn Redgrave. (Redgrave had one previous film role, a "blink and you'll miss it" uncredited bit part in Shoot to Kill (1960), filmed three years before this film.)
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.
One of the dogs on Squire Allworthy's estate is a Golden Retriever. It can be seen trying to follow Tom when he is banished from the estate. The film is set during the time of the Jacobite Rebellion which began in 1745. The Golden Retriever was first bred in Scotland in 1868, more than 100 years after the time when the film was set.
Squire Allworthy: [to Tom, when not expected to recover from a carriage accident]
I am convinced, my boy, that you have much goodness, generosity and honor in your nature. If you will add prudence and religion to those, you must be happy.
Squire Allworthy: [Upon discovering an abandoned baby in his bed, which they suspect Jenny, one of the servants, has put there]
Who is the father, Jenny?
