In this job, Caruso found hisrole models inHumphrey Bogart,James Cagney andEdward G. Robinson.[8] He said:
"The ethics of certain actors certainly had a power over me. These guys taught me how to be what I consider the real scum of the earth."[8]
Caruso's first movie appearance was in the 1980 filmGetting Wasted as Danny. He credits his role as Topper Daniels, "the cadet who nearly drowned", inAn Officer and a Gentleman (1982) as what got him noticed.[9] InFirst Blood (1982), the first installment of theRambo franchise, Caruso played Deputy Mitch Rogers, the youngest and only sympathetic member of Sheriff Teasle's (Brian Dennehy) department, who protests the abuse ofJohn Rambo (Sylvester Stallone) but is unable to prevent it and is later wounded by Rambo during the forest pursuit.

He made news by leaving the highlyrated show the following year (only four episodes into the second season) after failing to obtain the raise he wanted.[11][12] Caruso's decision to leave the series would later be listed in a 2010 issue ofTV Guide as #6 on a list of TV's 10 biggest "blunders".[13]
Caruso was unable to establish himself as a leading man in films. His appearances in the 1995 thrillersKiss of Death andJade were met with a negative reception from critics, with both films receiving mixed reviews and poor box-office takings, and Caruso was nominated for theGolden Raspberry Award for Worst New Star for these two roles.

In 2002, Caruso returned to television in his first successful role sinceNYPD Blue, starring as policeLieutenantHoratio Caine in theCSI spin-off seriesCSI: Miami. Caruso was the first actor in the franchise to appear as the same character on three of the fiveCSI programs. He was known for frequently using one-liners at the beginning of each episode. Many of these include Caruso putting on his trademark sunglasses mid-sentence, then walking off-screen just as the main theme starts. On an episode of theLate Show with David Letterman that aired on March 8, 2007, actor and comedianJim Carrey professed to being a fan of the show and went on to do an impersonation of Caruso, asking for an "intense close-up" from the camera, speaking in a raspy voice and putting on sunglasses. Caruso later said in an interview withCBS that he was impressed with the impersonation.[15]
In 2012,CSI: Miami was cancelled after 10 seasons due to a decline in ratings and the climbing cost of production.[16] Caruso was the only actor to appear in all 232 episodes of the series.
