The story/film was good until it got to Le Mans 24, but ‘based on a true story’.
The car Jann raced at Le Man was Greaves Motorsport’s Gibson LM P2, not an Ligier LM P3 - which isn’t eligible to race in the Le Mans 24. Jann drove absolutely brilliantly! He had only tested the car on two very brief occasions, a phenomenal achievement !
The Nissan GTR used in the film is correct.
