No-one can watch the trailer for the new Paul Walker documentary without crying

Paul Walker first made a name for himself in Hollywood in the 1999 movie Varsity Blues, and later as Brian O'Conner in the Fast and the Furious series. However, his career was tragically cut short when he passed away in 2013.

Walker was killed in a car accident in Santa Clarita, California. A statement posted to his social media accounts at the time read:

"It is with a truly heavy heart that we must confirm that Paul Walker passed away today in a tragic car accident while attending a charity event for his organization Reach Out Worldwide.

"He was a passenger in a friend's car, in which both lost their lives. We appreciate your patience as we too are stunned and saddened beyond belief by this news. Thank you for keeping his family and friends in your prayers during this very difficult time. We will do our best to keep you apprised on where to send condolences."

Once the news was spread online, to fans, friends and family alike, plenty of people took to social media to mourn the loss of the actor. For those that had spent years acting with him, it was particularly heartbreaking.

"Brother I will miss you very much," Vin Diesel wrote. "I am absolutely speechless. Heaven has gained a new Angel. Rest in Peace." Meanwhile, his other Fast and Furious co-star, Tyrese Gibson, wrote:

"My heart is hurting so bad no one can make me believe this is real Father God I pray that you send clarity over this cause I just don't understand My heart hurts it's broken no one can convince me that this is real.... Prayer warriors please pray real hard for his only child, his daughter and family..."

And plenty more Hollywood stars came out to pay their respects:

Now, nearly five years on from his death, there is a new documentary about the actor on the horizon. The film, titled 'I Am Paul Walker', has now released a new trailer, which is about as emotional as you would expect.

“That guy made the best of every single minute," director Wayne Kramer says in the trailer. "He lived five lifetimes.”

Actor Tyrese Gibson is also featured. “If you loved him the way we did, you would say, ‘Well why him and not us?’” he said. Some of the star’s family also speak in the documentary, including his uncle Rhett, who said Paul “made a difference in a lot of people’s lives”.

The trailer, which begins with an old family video of a young Walker in 1986, is heartbreaking for many fans out there, who took took to Twitter to express their sorrow in the wake of the teaser.

The documentary, which looks to explore both Walker's childhood and life in the public eye, is set to premiere on August 11.
