This paul walker tribute video from vin diesel will melt your heart

The start of a new year is a time to reflect, which is exactly what Vin Diesel did at the end of 2013. The result is an 18-minute tribute videoto his late "Fast & Furious" co-star Paul Walker, which Diesel posted on his Facebook page on Tuesday.

"You have always been so supportive, especially in these past two months," Diesel wrote to fans of their kind words about his friend, who was killed in a fiery car crash on November 30. "So, I wanted to share something personal that I worked on through the New Year, in honor of my brother Pablo … Paul."

In the video, titled "Vinbook: A glimpse … of Dom and Brian … off screen," we see the pair geeking out over cars and sharing laughs while doing press for the "Fast" franchise, screwing around off camera and having an in-depth, soul-searching talk about their motivations on the set of the "Unscripted" show.

In one of the happiest moments, the cast of "Fast" loudly sing "Happy Birthday" to an embarrassed Walker and wish for "another 15 years" working together. "It’s a blessing to be able to work with your brother on and off screen," Diesel says near the end before the words "Miss You" pop up.

Diesel said he went on a "very important" road trip over New Year’s inspired by Walker, "who was guiding me up the California coast." The soul-searching journey brought to mind a number of memories from the pair’s past, including an incident Diesel said he still can’t believe.

"The time when Paul and I closed down a press junket in LA… I believe it was the only time in history, that a junket was ever shut down due to driving," he wrote. "Haha, it was the last time the studio ever had cars at a junket that Paul and I were at."

He accidentally brought an old laptop on the trip and ended up getting "lost in the memories," which inspired him to put the tribute video together.

Diesel attended a private memorial service for Walker in Santa Clarita, California, last month and appeared at a public memorial in Valencia where he addressed the crowd about his fallen comrade. This week it was reported that Walker’s "Fast" character, Brian O’Conner, will be "retired" and not killed off in the upcoming "Fast & Furious 7" film that the actor was working on at the time of his death.
