The link was miscoded. This isn't the shot I was thinking of. The one I saw showed a much younger actor playing Tarkin. Or maybe what I saw was a shot of him out of makeup. Not sure.
Samatar, are you wondering who played Tarkin in ANH? If so, it's Peter Cushing and he is very well known as an actor from old 50s/60s/70s monster movies. Check his listing on IMDb. The guy has been in a ton of flicks.
