A Terrible Beauty (also known as The Night Fighters) is a 1960 drama film directed by Tay Garnett and starring Robert Mitchum, Anne Heywood, Dan O'Herlihy and Richard Harris.

Dermot O'Neill is recruited into the Irish Republican Army (IRA) when a unit is formed in his Northern Ireland town during World War II.

Dermot's brother Ned and sister Bella are ambivalent, but his girlfriend Neeve Donnelly ends their relationship, believing that the IRA will make a murderer of him.

Bella becomes concerned when her brother does not return home, so she finds Neeve and they consult Dermot's friend, a cobbler called Jimmy Hannafin, who believes that he knows what has happened.

The editor Arthur Tanner recalled that director Garnett "was an alcoholic unfortunately, although he was supposed to have been dried out... and Robert Mitchum and Richard Harris were the two principles so you can imagine there were a certain amount of problems on the picture.

"[4] In a contemporary review for The New York Times, critic Eugene Archer wrote: "While the nature of the material invites a penetrating examination of the mental anguish implicit in an unresolved civil revolt, the writer has not attempted to explore it in depth, and has confined himself to a surprisingly strained and superficial treatment of the theme.

As a result, the dramatic structure falters after establishing a promising situation in the early reels, and a brief lapse into unconvincing melodrama at the end seriously limits the film's modest pretensions.
