Principal photography began on December 13, 1993 in Los Angeles, California, with the courtroom sequences being filmed first. On January 17, 1994, filming at Triscenic Production Services Inc. in Sylmar was interrupted by the 1994 Northridge earthquake. Filming resumed two weeks after the quake, and in February, the production moved to Alcatraz Island in the San Francisco Bay. Filming there had to be done at night, because the National Park Service did not want to disrupt daily tourism in the daytime. More than 300 crew members had to be crammed in the prison cells. Production wrapped on March 12, 1994. Historical accuracy The film makes numerous changes to historical events. The real Henri Young was not convicted of stealing $5 to save his sister from destitution. He had been a hardened bank robber who had taken a hostage on at least one occasion and had committed a murder in 1933. Young was also no stranger to the penal system. Before being incarcerated at Alcatraz in 1936, he had already served time in two state prisons in Montana and Washington. In 1935 he spent his first year in federal correctional facilities at McNeil Island, Washington before being transferred to Alcatraz. The film ends with the fictional Henri Young being returned to the dungeons of Alcatraz in the early 1940s where he supposedly dies. In reality the real Young remained on Alcatraz until 1948 before he was moved to the United States Medical Center for Federal Prisoners at Springfield, Missouri where he stayed until 1954. While on Alcatraz he remained in the main cell block. Young was not kept in any dungeon as they had been closed almost a decade earlier. In 1954, Young was transferred to the Washington State Penitentiary at Walla Walla to begin a life sentence for the murder conviction in 1933. In 1972, after Young was released from Washington State Penitentiary at age 61, he jumped parole. According to
