Factual error: Sir Francis Walsingham was only a year older than Elizabeth.
Continuity mistake: In the love scene with Gia and Linda you can see a band-aid on Gia's middle finger on her left hand twice but the third time you see her left hand it's gone.
Continuity mistake: Whale commits suicide by drowning himself in the pool. When Clayton pulls him out the color of Whale's suit changes from black to brownish, and vice versa when Clayton throws him back in. Varying degrees of wetness should not be the reason as he should be drenched too while he is lying at the poolside. (01:33:40)
Continuity mistake: Near the beginning of the film, "Elvis" is driving Byron's car, and has a diamond horseshoe ring on. They show a close up of it as he's driving, and in a subsequent scene, the ring has been turned around.
Other mistake: When a Japanese newspaper is shown publicizing Jackie's performance, the headline above the photo actually reported that the Japanese budget had been approved by parliament.
Continuity mistake: In the final lap of the race with Pre vs. Frank Shorter the two runners round the last lap with Shorter leading the race. At first Shorter is leading in lane 1 with Pre following directly behind. Then Pre is suddenly in lane 2. For the final straight away, Shorter is now in lane 2 and Pre in lane 3. (Also a factual error as no runner leading a race would ever run in any lane other than the first which is the shortest distance). (01:36:00)
