'Dazed and Confused' Actor Nicky Katt Dead at 54

Nicky Katt — a recognizable character actor who appeared in dozens of well-known shows and movies — has died … TMZ has confirmed.

Attorney John Sloss — head of the firm that repped Katt, Sloss Law — confirmed Nicky’s death … though he did not provide any more details.

Nicky got his start in acting way back in the early 1980s … appearing in bit parts on “Fantasy Island” and “CHiPs.”

After recurring rolls on “Herbie, the Love Bug” and “The Get Along Gang” in the mid ’80s and grabbing a few more guest spots on “The Facts of Life” and “Uncle Buck,” Nicky gained mainstream recognition for his part as Clint Bruno in “Dazed and Confused” … a tough guy who fights Adam Goldberg’s Mike Newhouse.

Nicky played a number of tough guy characters and unsympathetic villains over the years … appearing in “A Time to Killer,” “Sin City,” “Boiler Room,” “School of Rock,” “The Way of the Gun,” “Monk,” “Law & Order” and many more movies and shows.

TV fans will probably most know him for his part as Harry Senate — a teacher in the his show “Boston Public.” Katt played the character in 49 episodes across the first three seasons of the show.

Many online are remembering Katt’s talent … and mentioning he always brought great performances to life onscreen — while lamenting that he never quite became a household name.

Katt was married to a woman named Annie Morse from 1999 until 2001.

He was 54.
