parents withdrew him from the Hollywood Professional School, which served child movie actors, and sent him to the public West Los Angeles University High School, instead. There, his grades dropped substantially, he was the target of ridicule for his previous film career, and he began to take drugs. He said later, "The other kids didn't accept me. They treated me as one apart. I tried desperately to be one of the gang. When they rejected me, I fought back, became belligerent and cocky—and was afraid all the time." At his request, Driscoll's parents returned him the next year to Hollywood Professional School, where in May 1955 he graduated. His drug use increased; in an interview years later, he stated, "I was 17 when I first experimented with the stuff. In no time I was using whatever was available... mostly heroin, because I had the money to pay for it." In 1956, he was arrested for the first time for possession of marijuana, but the charge was dismissed. On July 24, 1956, Hedda Hopper wrote in the Los Angeles Times: "This could cost this fine lad and good actor his career." In 1957, he had only two television parts, as the loyal brother of a criminal immigrant in M Squad, a long-running crime series starring Lee Marvin, and as an officer aboard the submarine S-38 in an episode of the World War II docudrama series The Silent Service. In December 1956, Driscoll and his longtime girlfriend, Marilyn Jean Rush (occasionally misspelled as "Brush"), eloped to Mexico to marry despite their parents' objections. The couple was later rewed in a ceremony that took place in Los Angeles in March 1957. They had two daughters and one son, but the relationship did not last. They separated, then divorced in 1960. Later roles Driscoll began using the name "Robert Driscoll" to distance himself from his youthful roles as "Bobby" (since 1951, he had been known to friends and family as "Bob", and in Schlitz Playhouse of Stars – Early Space Conquerors, 1952, was credited as "Bob Driscoll"). He landed two final screen roles: with Cornel Wilde in The Scarlet Coat (1955) and opposite Mark Damon, Connie Stevens, and Frances Farmer in The Party Crashers (1958). He was charged with disturbing the peace and assault with a deadly weapon, the latter after hitting one of two hecklers with a pistol who had made insulting remarks
