His first film appearance was in the 1980 film Getting Wasted, in which he played the part of Henry. Caruso then spent the better part of the next decade in supporting roles on the big screen, appearing in such films as An Officer and a Gentleman,, Blue City, Thief of Hearts, and China Girl. David Caruso also appeared in First Blood, the very first Rambo film.[1] If one looks closely, a very young Caruso is visible as one of the sheriff's deputies. He plays naive Deputy Mitch, who's clearly impressed with the fugitive John Rambo's skills. He can be seen a few times throughout the movie.

Caruso is also seen in a few scenes in Twins, as a parking lot attendant, with Danny DeVito and Arnold Schwarzenegger.

In television he had a recurring role as the gang leader of "The Shamrocks" on Hill Street Blues in the early 1980s. He also had a memorable two-episode appearance on the television series Crime Story, which ran from 1986 to 1988 on NBC.
