Best biography movie mistakes of 1998
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.
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).
