Charles Martin Smith (far right) played accountant Oscar Wallace in the 1987 movie version of "The Untouchables," a popular TV series that ran from 1959-1963. Wallace joins a team organized by Treasury agent Elliot Ness, played by Kevin Costner, to break up Al Capone's mob in Prohibition-era Chicago. They finally put Capone behind bars for tax evasion. Capone was played by Robert De Niro. Other members of Ness's Untouchables included Sean Connery and Andy Garcia. Wallace was based on a real-life accountant named Frank J. Wilson who joined the Treasury Department's Intelligence Unit in 1920 and later helped nab Lindbergh baby kidnapper Bruno Hauptmann by insisting that the serial numbers on the ransom money be properly recorded. Wilson later became chief of the Secret Service.
