Robert Arden (11 December 1922 – 25 March 2004) was a British-American film, television and radio actor[1] born in London.

"[2] Arden's most famous film appearance was as lead character Guy Van Stratten in Mr. Arkadin (1955), written and directed by Orson Welles.

Reportedly, Arden was shocked that Welles might consider him for the part and initially thought that the director's phone inquiry was a crank call.

[9] Mr. Arkadin did poorly at the box-office (but later received a cult following and all versions were part of a Criterion Collection box set).

Afterwards, Arden played a few other lead roles, in films such as The Depraved (1957) or The Child and the Killer (1959), but he worked mostly as a character actor, appearing in film, television and stage productions, perhaps most memorably as a high official who is hypnotized to take his own life by the adult Damien Thorn (played by Sam Neill) in Omen III: The Final Conflict.
