Brown began his acting career as a child of five and took part in many television and live performances. He appeared with
Van Johnson in a stage production of
The Music Man at the age of ten. Brown was 19 when he made his first major screen appearance in
Halls of Anger (1970), followed by
The Great Northfield Minnesota Raid (1972) and his breakthrough role as the
American Civil War draft dodger Drew Dixon in
Robert Benton's critically acclaimed
Bad Company (1972), co-starring with
Jeff Bridges. The publicity and promotion for this film was capped by an article in
Esquire introducing filmgoers to the "dashing, brooding Brown" in color photographs by
Chris von Wangenheim, along with a text mention of Brown's obituary collection focusing on little-known and forgotten Hollywood personalities. After playing opposite
Cybill Shepherd in
Daisy Miller, Brown concentrated on television throughout the 1970s, including the TV movie
The Disappearance of Aimee (1976), about evangelist
Aimee Semple McPherson, and numerous TV episodes. His final features were the crime drama
The Ultimate Thrill (1974) and
Joe Dante's
Piranha (1978). An authority on actors and film history, Brown was a contributor to
Scream Queens: Heroines of the Horrors by Calvin Beck and
Bhob Stewart. Published by Macmillan in 1978, the book features illustrated biographical profiles of 29 fantasy film actresses and directors. Brown did a similar survey, the unpublished
Unsung Heroes of the Horrors, covering the lives of some lesser known Hollywood talents, and he also contributed to various magazines, including
Films in Review and
Castle of Frankenstein. The book
Who Was Who on Screen Third Edition, by Evelyn Mack Truett was dedicated to Brown, whom she credited with giving data support for the previous edition. ==Personal life and death==
