Dan Seymour (February 22, 1915 – May 25, 1993) was an American character actor who frequently played villains in Warner Bros. films. He appeared in several Humphrey Bogart films, including Casablanca, Key Largo, and To Have and Have Not.
He should not be confused with Dan Seymour, the announcer of Orson Welles' Halloween broadcast of The War of the Worlds and other radio programs.
On May 25, 1993, Seymour died of a stroke in Santa Monica, California. He was buried at Hillside Memorial Park in Culver City, California.
