Chicago Reader review:
Released in 1975, near the end of Arthur Penn's most productive period (which began in 1967 with Bonnie and Clyde), this haunting psychological thriller ambitiously sets out to unpack post-Watergate burnout in American life. Gene Hackman plays an LA detective tracking a runaway teenager (Melanie Griffith in her screen debut) to the Florida Keys while evading various problems of his own involving his father and his wife. The labyrinthine mystery plot and pessimistic mood suggest Raymond Chandler and Ross MacDonald, and like them screenwriter Alan Sharp has more than conventional mystery mechanics on his mind. One of Penn's best features; his direction of actors is sensitive and purposeful throughout. With Jennifer Warren, Susan Clark, Edward Binns, Harris Yulin, Kenneth Mars and James Woods.
Here (and above) is the trailer.
