Subtract a decade or so from Cruz Castillo's father, and you have a much younger man. Indeed, Henry Darrow is dashing and handsome as a ruthless information broker in the second-season "Wonder Woman" episode "I Do, I Do," years before his spin as Rafael Castillo on our beloved "Santa Barbara."
Clad in '70s suits that veer to the tasteful side (believe it), he tries to pry secrets out of the all-too-suspecting Diana Prince, who is posing as the wife of a powerful presidential adviser. No-go on that -- she's just too wise for him. He also tries to dispatch with another smart would-be victim via a dangerously trained horse named Satan. Ouch. He's just an all-around bad guy! Good thing he showed his kinder, gentler side when he became Grandpa to Chip and Adriana!
See Darrow in the November 1977 episode at the WB, and look for full BRBTV synopses of the "Wonder Woman" episodes at the IMDb.
