"Scotty" Gets Walk of Fame Star
linuxwrangler writes "Actor James Doohan, aka Scotty on the original Star Trek series received his star on the Hollywood Walk of Fame today. This is expected to be Doohan's last public appearance as he suffers from Parkinson's disease, diabetes and lung fibrosis as well as recently diagnosed Alzheimer's disease."
