Film critic James King said the industry had been left in shock by Scott's death, adding that the director would be remembered for his "edge-of-your-seat thrillers".
He told Sky News:
Go buy his films, watch his films, and you'll see an incredibly confident director, so for that person to have taken their own life just seems utterly bizarre.
I think he'll be remembered as one of the ultimate action directors. He wasn't ashamed by that.
Maybe some critics had a go at him because his films weren't intellectually challenging. But when they looked as good as they did, who cares? They were incredibly stylish.
He trained in fine art, he was an artist.
Tony Scott's body was recovered from Los Angeles Harbour water several hours after members of the public called police at around 12:35pm local time (7.30pm BST) to report that someone had jumped from the Vincent Thomas Bridge, the Associated Press reports.
The reports adds that a note with contact information was found in Scott's car and a suicide note was later found in his office.
