J.A. Preston Body Heat (1981)
J.A. Preston (born October 22, 1939, Camden, New Jersey) played Det. Oscar Grace in Body Heat (1981) — the investigating detective who likes Ned Racine, tries to warn him off, and ultimately listens to his prison-library reconstruction without believing a word of it.
Preston was a working character actor
Preston had been working steadily in film and television since the late 1960s — The Out-of-Towners (1970), The Anderson Tapes (1971), Network (1976), Remember My Name (1978), and an extensive television résumé that included Mannix, Hill Street Blues, Lou Grant, and St. Elsewhere. His face and voice were familiar to American television audiences without being identified with any single role. (wikipedia)
Oscar Grace is the only character who genuinely likes Ned
What Preston brought to Oscar Grace was patience. Grace is the film's moral conscience — the cop who likes Ned, who eats pie at the diner with Lowenstein, who delivers the heat-thesis line ("When it's hot, people try to kill each other"), who shows up at Ned's apartment with Lowenstein to formally warn him off Matty,b27 and who ends the film hearing Ned's reconstruction in a prison library and walking out with the line "Is that what you've been waiting for?"b42
Preston played all of this in a single register. Grace doesn't get angrier as the case develops; he gets sadder.
"Preston gives Oscar Grace the saddest performance in the film. He likes Ned. He keeps trying to save him. By the prison-library scene he has stopped trying. The exhaustion is in the eyes." — Roger Ebert, RogerEbert.com (Great Movies, 2002)
The prison-library scene
The film's penultimate beat is a long two-hander in the prison library: Ned reconstructing the long con for Oscar, Oscar listening, the camera staying with both men. Preston's job is to hear a story he believes might be true and refuse to act on it because the money cannot be found. The line he delivers — "Is that what you've been waiting for?" — is the film's structural goodbye to its protagonist.
"Oscar listens to Ned the way a brother listens to a brother who has done something irreparable. He doesn't say what he believes. He gives Ned the space to finish. Then he leaves. The performance is one of the great supporting turns of the early 1980s." — The A.V. Club, The A.V. Club (2021) (general retrospective)
After Body Heat
Preston continued to work steadily on television and in film — A Few Good Men (1992), where he played Judge Randolph; The American President (1995); episodes of NYPD Blue, L.A. Law, and Picket Fences. He has spoken rarely about Body Heat in public interviews.
