Why Robert Clohessy Was Only Supposed To Be In One Blue Bloods Episode

In an interview with Main Street Magazine, Robert Clohessy revealed that his role as then-Sergeant Gormley was supposed to be a one-off, but he can thank his great chemistry with one particular "Blue Bloods" star for his lengthy tenure with the show. "I was originally cast for one show to be Danny's boss in the precinct," Clohessy said. "We got along really well on set and, before long, I was part of the regular cast."

To be completely fair to Clohessy, though, getting along with Wahlberg may have helped him escape the one-episode wonder status, but it's pretty likely that his own talent helped quite a bit. After all, before his lengthy tenure with "Blue Bloods," he was already an experienced hand at playing various officials in high-profile shows. You might remember him as Officer Patrick Flaherty in "Hill Street Blues," or as Officer Sean Murphy in HBO's prison drama "Oz." In fact, he's such a go-to actor to portray law enforcement figures that while he was already with "Blue Blood," he even became a part of the Marvel Cinematic Universe, thanks to his role as a police sergeant in "The Avengers."
