Vin Diesel got so choked up talking about his friend and co-star Paul Walker, he couldn't talk.
Vin was at an L.A. screening of "Furious 7" when he talked about his "best friend." He was overcome by emotion.
Vin told the crowd, as far as he's concerned the movie is an homage to Paul, who died in a car crash in November, 2013.
The video is very moving ... the crowd jumps in to show empathy and support for Vin, who struggles to continue.
