Factual error: In the first scene, the raid on the gambling party, the policemen all wear white shirts. The scene is set in 1958 and the Metropolitan Police did not switch from blue shirts to white until c.1970.
Killer With a Long Arm - S1-E4
Factual error: The assassination attempt takes place on Wimbledon Finals Day, yet there seem to be other matches going on at the same time, which doesn't happen when the final's occurring.
Part 1 Roots: The Saga of An American Family - S1-E1
Factual error: The slave ship 'Lord Ligonier' flies the White Ensign. This has always been reserved for the Royal Navy; British merchant ships (as American ships were in 1765) have flown the Red Ensign since 1674.
Factual error: In this episode, Jack asks Felipe how he can bring Mr. Angelino to The Apartment, in which he answers "We took the Santa Monica freeway to the Cloverfield exit." The Cloverfield exit is in reality, a good 2 miles or so from the beach (2 other exits are much closer to beach than this). Yet throughout the series, it is implied that The Apartment is very close to the beach (3 blocks is stated by Jack in a much earlier episode). Why a far exit for a beach-area apartment?
Suggested correction: Correcting my own entry: I just recently saw this episode for the first time in a long time. Felipe actually says the "Centinela" exit (not "Cloverfield"). Technically this even adds to the mistake as it is one exit even FURTHER from the beach area apartment. Now 3 miles away exiting (instead of 2 as previously submitted).
