The Timeless Media Group DVD contains a 46-minute syndication edit. The scene featuring Steve Pendleton (Dr. Nielsen) appears to have been left on the cutting room floor.
For this series, Hal Holbrook (Sen. Hays Stowe), Sharon Acker (Erin Stowe), and Cindy Eilbacher (Norma Stowe) carried over from the television movie A Clear and Present Danger (1970). The role of advisor Jordan Boyle was recast with Michael Tolan (replacing Joseph Campanella, who was then co-starring in The Bold Ones: The Lawyers (1969)). Michael Bell, who played Stowe's chauffeur Elliot Morse in the movie, appears here as FBI agent Paul Shaw.
