Vin Diesel Pays Tribute to Paul Walker as Filming For Fast 8 Begins

Filming for Fast 8 is underway, and on Saturday, Vin Diesel took to Instagram to pay tribute to his late friend Paul Walker. Along with a nostalgic photo of the two, Vin wrote a touching message that read, "Many of the crew members who have worked on several of the past Fast films are here again to help us make something special. One of them at the end of the week came up to me and said wow what we are capturing on film is excellent... And then looked at me and said Paul would be proud. #wemakethemwithourhearts."

The actor appears to be having a tough time on set. Earlier in the week, he explained in a short clip that "coming into shooting Fast 8, I knew that it was going to be a darker road," adding, "It's amazing regardless of how successful you are that you have to go into a dark place to channel a character, to feel the character." Take a look at Vin's post above, then look back at Paul's best Hollywood moments.
