Factual error: In season 2, they spend a lot of time at a Malibu Beach house. There are a few scenes across a few episodes when they are headed from Malibu into Los Angeles, but the scenes are shot on the coast in El Segundo, roughly 30 miles out of the way and definitely not a straight shot from Malibu.
Episode #1.1 - S1-E1
Factual error: There is a view of the night sky in southern Africa. However, both the Big and Little Dippers (along with Polaris) are visible. In general, these constellations are not visible in the southern hemisphere, and where they are (North of 1° South latitude) they are very close to the horizon. The Big Dipper (Ursa Major) is to the left of the screen and Polaris (part of the Little Dipper = Ursa Minor) in near the top-center. This occurs shortly after the lion cub scene. (00:44:00)
Factual error: Both Inspector Shaw and Chief Inspector Bailie wear their medal ribbons in the wrong order. The Golden Jubilee Medal is worn first, followed by the Diamond Jubilee Medal, followed by (for Bailie) the Long Service and Good Conduct Medal.
