Why were Paul Walker and Vin Diesel chased by helicopters in real life?

In the latest episode of Unscripted, the "Fast & Furious 6" stars talk about their wild night at a real-life illegal street race, what "Fast" characters are the most badass, and how many more films are left in the action franchise's future.

In the latest adrenaline-pumping "Fast" installment, Agent Hobbs (Dwayne "The Rock" Johnson) enlists Dom (Diesel) and his team to bring a rival gang, led by Owen Shaw (Luke Evans), to justice in exchange for a clean criminal record. Not a bad deal.

Watch Diesel and Walker go Unscripted above. "Fast & Furious 6" speeds into theaters May 24.
