A veteran of Chicago's free-form Organic Theatre, the boyish, personable John Heard won the Theatre World Award for his performance in the 1976 play Streamers, and two years later was the recipient of the Obie Award for two separate off-Broadway productions. He made his film bow as the harried correspondent for an underground newspaper in Joan Micklin Silver's Between the Lines.
In Silver's 1979 Head Over Heels, Heard again received top billing, this time as the obsessive ex-lover of Mary Beth Hurt. One of his first mainstream leading roles was in Paul Schrader's erotic thriller Cat People (1981). Heard was agreeable, if a little bullheaded, as Macaulay Culkin's dad in the two Home Alone films; less agreeable was his portrayal of Tom Hanks' abrasive business rival in Big (1988) On television, Heard was seen as the tormented Reverend Dimmesdale opposite Meg Foster's Hester Prynne in the PBS production of The Scarlet Letter, and was heard as one of the celebrity voices on the made-for-cable Dear America: Letters Home From Vietnam (1987). John Heard was at one time married to actress Margot Kidder. ~ Hal Erickson, All Movie Guide.
