In September 1951, Laven formed a production company with
Jules V. Levy and
Arthur Gardner, both of whom he had met while working in the First Motion Picture Unit. The company, which eventually became
Levy-Gardner-Laven, was initially called "Allart Pictures, Inc." The company opened offices at Goldwyn studios and announced plans to begin casting on their first feature,
Without Warning!, a thriller about a psychopathic killer on the loose. In May 1952,
Hedda Hopper announced the arrival of the new team as follows: The trio's second feature was
Vice Squad, a 1953 detective drama directed by Laven and starring
Edward G. Robinson and Adam Williams. The third feature,
Down Three Dark Streets, was another
semidocumentary-style
film noir starring
Broderick Crawford as an FBI agent. The film's climax took place around the
Hollywood Sign. A newspaper review of the 1954 film noted the promise of the three young producers: In 1956, Laven went out on his own to direct
The Rack, a drama starring
Paul Newman and
Lee Marvin about a soldier who is court-martialed for collaborating with the enemy after spending two years in a
North Korean prison camp. The film was based on a
United States Steel Hour program written by
Rod Serling. In 1957, Levy-Gardner-Laven team turned their focus to the popular science fiction and monster genres. Laven received directing and producing credits on
The Monster That Challenged the World, a feature about an army of giant mollusks that emerge from the
Salton Sea in
California's
Imperial Valley. A review in the
Los Angeles Times called the film "distinctly chilling," noted that "Laven never lets the tension slacken," and described the plot as follows: The trio followed with a pair of vampire movies,
The Vampire, a 1957 release about a small-town doctor who mistakenly ingests an experimental drug made from the blood of vampire bats, and
The Return of Dracula, a 1958 feature about a vampire who murders a Czech artist, assumes his identity, and moves to the United States. In the late 1950s, Laven also directed
Slaughter on Tenth Avenue (1957), a crime drama set on the docks starring
Richard Egan and
Walter Matthau, and
Anna Lucasta (1958), a feature starring an all-African American cast that included
Eartha Kitt and
Sammy Davis Jr. ==
