in Boston Legal (3x18), "Son of the Defender", the producers used footage from a 1957 "Studio One" two part drama, "The Defenders" (9x20 and 9x21), featuring William Shatner. This is the complete, original episode: A young criminal attorney and his firm-owning father defend a 19 year-old on trial for a murder that he swears he did not commit. Personal conflicts arise with the attorney and his father while the prosecution puts on a dramatic and convincing argument of guilt. (thetvdb.com)
