Actors have been re-used in different roles time and again in Trek (Mark Lenard, David Warner and John Schuck immediately come to mind, but there are actually dozens).
BUT (and this was bugging me last night for some reason)...sometimes it's kind of jarring. Example: Merritt Buttrick and Judson Scott, each of whom had notable big screen deaths (TSFS and TWOK respectively) co-starring as drug-addicted aliens in the TNG episode "Symbiosis".
Kirk's son and Khan's right-hand man appearing together really took me out of that episode when it first aired.
Any others that sort of "throw everything off" by just being there come to mind?
