O'Farrell is a 1968 American comedy film directed by Frank Tashlin and starring Bob Hope, Phyllis Diller, and Jeffrey Hunter.

Among his problems are the Navy personnel making life difficult for him and his Army buddies, an officer trying to emulate John Paul Jones, a hoped-for delivery of morale-boosting nurses turning out to be six men, the ugliest woman (Diller) ever to wilt a bouquet of flowers, and a Japanese soldier who has been hiding from everyone else and hiding something else as well.

[3] Renata Adler of The New York Times gave an unfavourable review, complaining about "the endless progression of unfunny lines.

O'Farrell" is how completely it neglects the humorous possibilities of film," although he found enough good in the tight storytelling, Frank Tashlin's directing and Mako's performance to award two-and-a half stars.

"[6] Leonard Maltin stated, "Of the many terrible Hope comedies of the 1960s, this may be the worst," and gave it his rock-bottom rating of BOMB.
