Richard Basehart in He Walked by Night (dir. Alfred Werker, 1948).
The docu-style police procedural that Dragnet was based on. Richard Basehart is flawless as a very blank young electronics whiz and cop killer. Nice touch: he has a cute dog. Jack Webb has a small role as a forensics expert. The finale in the LA storm drains is a fine showcase for John Alton's cinematography--too bad the print I saw was so poor.
