American actor (born 1950) who played Lon Suder, the murderous Betazoid Maquis crewman who finds a measure of peace through a mind meld with Tuvok, in three episodes of Voyager.
Brad Dourif is an American actor, nominated for an Academy Award for One Flew Over the Cuckoo's Nest and known as the voice of Chucky in the Child's Play films, Wormtongue in The Lord of the Rings and Doc Cochran in Deadwood.
In the second season of Voyager he plays Lon Suder, a Betazoid former Maquis who kills a crewmate for no reason he can explain. In Meld, Tuvok joins minds with him to understand his violence, giving Suder some self-control while unsettling the Vulcan's own.
He returns in Basics, Part I and Part II, where the confined Suder is one of the last people left aboard after the Kazon seize the ship and dies helping to retake it.
