A loss of character

Sad to read about the death of actor Ron Glass, who was probably best remembered for his role on Barney Miller, but who gave depth and insight to the part of Shepherd Book in the sadly short-lived science fiction TV series Firefly (and the wrap-it-the-series movie Serenity).

Veteran character actor Ron Glass of Barney Miller and Firefly fame dead at 71

He definitely had "range".
