evidence: Vin Diesel was left "choking back tears" after witnessing his stunt double tragically fall on the set of Fast And Furious 9 on Monday. [...] "The stuntman fell at least 30ft — maybe a bit more," a source told British newspaper The Sun. "Vin Diesel was seen on set seconds after. He looked ashen, totally in shock and blinking back tears. He saw what happened." [...] Diesel has had several brushes with tragedy in the past. His stunt double Harry O’Connor was killed filming a para-sailing scene for 2002 action flick xXx in Prague while performing a paragliding stunt in the actor’s place. And his Fast and Furious co-star Paul Walker died aged 40 in a car crash off-set during filming of the franchise’s seventh film in 2013.
