A 2008 Documentary film narrated by Jason Statham about the Audi racing team's attempt to win the 2008 24 Hours of Le Mans in the Audi R10 TDI against a car that had been faster all year, the Peugeot 908 HDi FAP. Shortly after its initial airing on ESPN, it was made available for free download on iTunes.
In 2012, a sequel was made documenting the 2011 race called Truth in 24 II: Every Second Counts.
- Badass Driver: Many — notably including Peugeot's Jacques Villeneuve, one of an elite few who have won both the Formula One World Championship AND the Indianapolis 500 — but for Le Mans specifically there is Tom Kristensen, who had won a record seven times at Le Mans in only nine appearances. He makes it eight out of ten by the end of the film.
- Chekhov's Gun: The first line of the film is "It always rains at Le Mans."
- Cool Old Guy: Justified, as a lot of former or ex-Formula One drivers move to sportscar racing. But it applies best to the #1 Audi, whose three drivers had a combined age of 132!
- Dramatization: While all the footage is of true events, at several places facts are elided to give a more dramatic impression — for example, it is nowhere mentioned that the same model Peugeot had raced against Audi in the 2007 series.
- Epic Race: Le Mans is probably the most famous Real Life example of one, and the properties of the race that make it fit this trope are heavily emphasized in the film.
- Foregone Conclusion: It shouldn't be a surprise that an Audi wins, but out of the three cars they enter it's the #2 that is victorious.
- Fridge Horror: In-Universe; one of the clips from races earlier in the season shows that, during the 1000km of Monza, a car lost control and flew through the air inches from Allan McNish's Audi — a fact he was unaware of until watching the replay the next day.
- Mission Control: Each car has an engineer assigned to this job for the race — Car #2's Howden "H" Haynes gets the most screentime.
- My Greatest Second Chance: The race is treated in this way by the #3 Audi's Mike Rockenfeller, who had crashed his car at the previous year's Le Mans.
- Stealth Pun: The quote at the top of the page. The "four rings" Capello refers to make up Audi's logo.
- Title Drop: In the introduction, Statham describes the race as Audi's "moment of truth — 24 hours of truth."
- The Big Race: Le Mans, of course.
