Bruce Weitz

Best known for his scruffy, quirky-acting role as undercover cop Sgt. Michael "Mick" Belker in the 1980s TV series Canción triste de Hill Street (1981) who tended to call all criminals "hairball," and whose canine instincts had him habitually growling, biting offenders and barking at other dogs.

Figuring out Belker happened from the outside in. I was planning my audition, I had about 10 days to work on it, and I was thinking about what he would wear. And when I finally got together a costume, which was pretty much what he looked like on the show week to week, I started to get a feeling for what he was.
