The Mysterious Affair at Styles - S3-E1
Factual error: Poirot is taking a break from the prosecution' speech and is walking with Hastings, explaining to him Mary Cavendish's jealousy. In the street, they pass by a truck (registration plate MR 5496) that is a Morris-Commercial 1-Ton model. Morris began productions in the early 20s, and we are in 1917 for this episode. (01:17:45)

Factual error: At the local food store, Poirot is talking with the shopkeeper. In the background are plenty of food packages that show the great care for authenticity that is a mark of the series. I feel like disputing at least a couple; the Polly box with a parrot is a Taormina American-made can that should be a product of the 20s, and the Brown and Polson's Patent Corn Flour has a claim on the box that says "65 years world-wide reputation." The patent is a 1856 one and the annexed name is from 1859 (previous ads with established date show that year as the one they started counting from); in 1917 the box would have not said "65 years", it hadn't even reached 60.

Factual error: The movie opens with Hastings watching a news film about the "New Flanders Offensive." It says that on "7th June 1917 General Haig attacks Ypres", but at the beginning of the year Sir Douglas Haig was promoted to Field Marshall. A news propaganda reel would surely have called him with the appropriate title. (00:00:35)
