(written from a Production point of view)
Robert Bruce is an actor who portrayed a background Klingon in Star Trek VI: The Undiscovered Country. He received no credit for this appearance and was identified by the name tag of his belt which was sold off on the It's A Wrap! sale and auction on eBay and originally designed for stunt actor Scott Leva. Leva had to use a different belt because of his rigging harness so Bruce got this one.
