Reaction to Scott's death poured out Monday, with directors, actors and fans mourning the news.
"Being around you was always the ultimate experience -- intensity, vitality and celebration. Pure rock and roll and great cigars. Your warmth and generosity was palpable to all us. You treated everyone with care and respect," said actor Edgar Ramirez, who starred in Scott's 2005 film, "Domino."
"You always focused on the subtleties, taking the best out of us. I am proud to be your friend, and although I won't be seeing you for a while, you will live on in the laughter of our memories of you."
"Tony Scott as a friend and a mentor was irreplaceable. Tone, wherever you are, I love you man. RIP," director and producer Joe Carnahan said on Twitter.
Carnahan recounted how when his movie "The Grey" was finished, Scott called to tell him he had seen it. He told Carnahan it was great and not to allow anybody to change anything in it.
"Tony always sent personal, handwritten notes & always drew a cartoon caricature of himself, smoking a cigar, with his hat colored in red," Carnahan said in a post.
Scott directed his last film, the train thriller "Unstoppable" starring Washington, in 2010.
"For me, it was the most challenging movie of my life, and the most dangerous because I'm shooting 90 percent of the movie on a train that is running between 50 and 70 mph," Scott told CNN at the time.
Scott's reputation in Hollywood was low-key.
"He wasn't a showy kind of guy," longtime entertainment reporter Jeanne Wolf told CNN.
Scott was often seen sporting a frayed, faded red ball cap on movie sets and at red carpet premieres.
The ball cap, Wolf said, was his trademark.
While Scott's movies garnered box office success, they never received the acclaim that generated Academy Award nominations.
In 2002, the Scott brothers won an Emmy for the television movie "The Gathering Storm."
Scott also was nominated for the Emmy as a producer for the CBS drama "The Good Wife."
"So very, very sorry to hear of the death of Tony Scott," actress Martha Plimpton, who appeared in "The Good Wife," said via Twitter.
Among his last projects was serving as an executive producer on the TV miniseries "Coma," which is due to air this year.
