Montgomery Scott was played by actor James Doohan in all of the character's television and cinematic appearances. Doohan lost the middle finger on his right hand during the Allied invasion of Normandy on D-Day. However, Scott has a right middle finger within the Star Trek storyline: any time a closeup is seen of Scotty's right hand (working the transporter controls, etc.) someone else's hands are used, and when Scotty appeared in wide shots he usually hid his right hand from the camera. His loss was most evident in TNG: "Relics", where the missing finger can be clearly seen in wide shots while talking to Captain Picard on the holodeck recreation of the original Enterprise bridge.

Edit: sad sam provršljao Wikipedijom i piše da ga je pogodilo šest metaka koje je slučajno ispalio jedan nervozni vojnik, njegov suborac - četiri su ga pogodila u noge, jedan u srednji prst, a šesti je poletio u prsa i zaglavio se u tabakeri za cigare
