Seymour Joseph Cassel (January 22, 1935 – April 7, 2019) was an American actor.
Cassel first came to prominence in the 1960s in the pioneering independent films of writer/director John Cassavetes. The first of these was Too Late Blues (1961), followed by Faces (1968), for which he was nominated for an Academy Award and won a National Society of Film Critics Award. Cassel went on to appear in Cassavetes' Minnie and Moskowitz (1971), The Killing of a Chinese Bookie (1976), Opening Night (1977), and Love Streams (1984).
He also appeared in a number of independent and Hollywood film productions. Notable films he was featured in include Coogan's Bluff (1968), The Last Tycoon (1976), Valentino (1977), Convoy (1978), Johnny Be Good (1988), Mobsters (1991), In the Soup (1992), Honeymoon in Vegas (1992), Indecent Proposal (1993), Beer League (2006), and Fort McCoy (2011). Like Cassavetes, Wes Anderson frequently cast Cassel - first in Rushmore (1998), and then in The Royal Tenenbaums (2001), and finally in The Life Aquatic with Steve Zissou (2004).
