Edward Woodward suffered a heart attack in the summer of 1987. Accordingly, the producers needed to find a quick replacement while Woodward recuperated.

Richard Jordan was also brought on as embittered former operative Harley Gage, and stayed for eight more episodes.
Edward Woodward was nominated for an Emmy for Outstanding Lead Actor in a Drama Series five years in a row even though the show aired for four years.

NOTE: Even though the show ran for four seasons, it started in 1985, and ended in 1989. Therefore, his nominations were for 1985, 1986, 1987, 1988, and 1989. A total of one nomination per year.
