William Robert Stalker (3 August 1948 – 28 November 1981) was a New Zealand actor, most famous for his roles in television, both in his native country and Australia.

Fanelli soon proved to be one of the show's most popular characters, and when Skyways was cancelled in 1981 the character was quickly moved to the police serial Cop Shop, with Fanelli re-entering the police force heading Riverside CIB as a Detective Sergeant (read TV Times on Stalker's run in both soaps and his sudden death).

However, on 28 November 1981, during a weekend break between taping his final scenes for Cop Shop, he was killed when his motorcycle slid and collided with a car in wet weather in Toorak, Victoria.

During his time in Blerta, he met Jazz singer Beverly Jean Morrison, who went under the professional name of Beaver, with whom he had two daughters, Fritha and Kate Stalker.
