There are a lot of orcs that are mentioned by name in the Lord of the Rings books; Ugluk, Grishnakh, Mauhur, Gothmog, etc.
But are there any mentions of their names in Peter Jackson's movie trilogy?
I've had a read through all three film scripts...
...as well as the scripts for the various special editions. Although several Orcs and Uruk-Hai are mentioned by name in the script notes (notably Lurtz and Grishnákh) none of them are mentioned within the dialogue itself.
