Webb had a featured role as a crime lab technician in the 1948 film
He Walked by Night based on the real-life murder of a
California Highway Patrolman. The film was made in
semidocumentary style with technical advice/assistance provided by
Detective Sergeant
Marty Wynn of the
Los Angeles Police Department. It was this film that gave Webb the idea for
Dragnet.
After getting much assistance from Sgt. Wynn and legendary LAPD chief
William H. Parker, Dragnet hit radio airwaves in 1949 (running until 1954) and then television in 1951 on the
NBC network. Webb starred as Sgt. Joe Friday, and
Barton Yarborough co-starred as Sgt. Ben Romero.
Webb was a stickler for attention to detail. He believed that viewers wanted "
realism" and strove to give it to them. Webb had tremendous respect for the people in law enforcement. He often mentioned in interviews that he was angry about the "ridiculous" amount of abuse to which police were often subjected by the press and the public. He said that he wanted to perform a service for the police by showing them as low-key working class heroes. In 'Dragnet' he moved away from earlier portrayals of the police in shows such as 'Jeff Regan' and 'Pat Novak', which often showed them as brutal and even corrupt.
Despite his reputation for accuracy, he wasn't above bending the rules. According to one
Dragnet technical advisor, he (the advisor) pointed out that several circumstances in one episode were extremely unlikely in real life. "You know that, and now I know that. But that little old lady in Kansas will never know the difference," Webb said in response.
In 1950, Webb appeared alongside future
Dragnet partner
Harry Morgan in the film noir
Dark City.
The year
1952 saw
Dragnet become a successful television show. Unfortunately, Barton Yarborough died suddenly of a heart attack, and Barney Phillips (Sgt. Ed Jacobs) and
Herbert Ellis (Officer Frank Smith) temporarily stepped in as partners. In 1952, veteran radio and film actor
Ben Alexander debuted as the second incarnation of jovial, burly Officer Frank Smith. Alexander proved to be a popular addition to the series as Webb's detective partner and remained a cast member until the cancellation in 1959.
Dragnet began with the narration "The story you are about to see is true. Only the names have been changed to protect the innocent." At the end of each show, the results of the trial of the suspect and severity of sentence were announced by
Hal Gibney. Webb frequently re-created entire floors of buildings on soundstages, such as the police headquarters at Los Angeles City Hall for
Dragnet and a floor of the
Los Angeles Herald-Examiner Building for the 1954 film.
During the early days of
Dragnet, he continued to appear in other movies, notably as the best friend of the main character in the 1950
Billy Wilder film
Sunset Boulevard.
Webb's personal life was better defined by his love of
jazz than his interest in police work. His life-long interest in the
cornet and racially tolerant attitude allowed him to move easily in the jazz culture, where Webb met singer and actress
Julie London. They married in 1947 and raised two children. They later divorced, and Webb married three more times.
In 1951, Webb introduced a short-lived radio series,
Pete Kelly's Blues, in an attempt to bring the music he loved to a broader audience. That radio series became the basis for a 1955
movie of the same name. However, neither the radio series nor the movie resonated with the audiences of the time.
In early 1967 Webb produced and starred in a new color version of
Dragnet for NBC. This version co-starred
Harry Morgan as Officer Bill Gannon. (Ben Alexander was unavailable, as he was co-starring in
Felony Squad on
ABC.) The show's pilot, originally produced as a made-for-TV movie in 1966, did not air until 1969. The series itself ran through 1970.
Beginning in 1968, in concert with
Robert A. Cinader, Webb produced NBC's popular
Adam-12, which focused on LAPD uniform officers Pete Malloy (
Martin Milner) and Jim Reed (
Kent McCord), which ran until 1975.
In 1968 Webb performed, in Joe Friday character, the classic "Copper Clappers" sketch during an appearance on
The Tonight Show where a pokerfaced Webb echoed
Johnny Carson's equally-deadpan robbery report where all the details started with "Cl" or least the letter C.
In the early 1970s, Webb produced
The DA with
Robert Conrad and
O'Hara: US Treasury with
David Janssen. These were short-lived, but another show,
Emergency!, proved to be a huge success, running from 1972 to 1977, with ratings occasionally even topping its timeslot competitor,
All in the Family. Webb cast his ex-wife, Julie London, as well as her second husband and
Dragnet ensemble player
Bobby Troup, as nurse Dixie McCall and Dr. Joe Early.
