[2] In the two previous seasons, Donahue had portrayed the detective Sandy Winfield, II, on another ABC/WB series, Surfside 6, set on a houseboat in Miami Beach.

"[5] During his Warner Brothers period, Eisley appeared in one episode of Jack Webb's Pete Kelly's Blues (1959) and in Portrait of a Mobster (1961).

In 1964, Eisley acted as master of ceremonies at a "Project Prayer" rally attended by 2,500 people at the Shrine Auditorium in Los Angeles.

Eisley was joined at the event by Walter Brennan, on whose series The Real McCoys he had once been a guest star, Rhonda Fleming, Lloyd Nolan, Dale Evans, Pat Boone, and Gloria Swanson.

[6] Syndicated columnist Drew Pearson claimed in his "Washington Merry-Go-Round" column that Project Prayer had "backstage ties" to the anti-Communist John Birch Society.

Pearson noted that the principal author of the prayer decisions, Chief Justice Earl Warren, was a Republican former Governor of California and that most mainline denominations had endorsed the Court's rulings.

In 1965, Eisley was cast as an attorney in an anti-pornography institutional film entitled "Printed Poison"; produced by the "Citizens For Decency" movement.

His most memorable role in film was as Griff in The Naked Kiss (1964), Sam Fuller's controversial attack on alleged American small town hypocrisy.

Eisley became known as a cult schlock star for his appearances in One Way Wahine (1965), Antonio Margheriti's Eurospy film Lightning Bolt (1966) and The Navy vs. the Night Monsters (1966).

He starred in David L. Hewitt's Journey to the Center of Time (1967), The Mighty Gorga (1969), and The Tormentors (1971) as well as Al Adamson's Dracula vs. Frankenstein (1971) and Ted V. Mikels's The Doll Squad (1975).

He appeared in other dubious delights such as Oliver Drake's They Ran for Their Lives (1968) and The Mummy and the Curse of the Jackals (1969), The Killers (1971) alongside Cameron Mitchell, Monstroid (1980) and Fred Olen Ray's Deep Space (1988).
