Of an entirely different order is Brennan's magnificent performance as Pop Gruber, an aging grifter in Nobody Lives Forever (November 1, 1946), starring John Garfield as a con man, Nick Blake, who eventually goes straight after falling in love with Gladys Halvorsen (Geraldine Fitzgerald, in the prime of her beauty). The script by W. R. Burnett, one of masters of film noir, provides not just Brennan, but also George Coulouris (Doc Ganson) with more dimension than is usually accorded heavies in crime dramas.
