Gateworld reported that Don S. Davis, who played Maj. Gen. George Hammond on SCI FI Channel's Stargate SG-1 for seven seasons, died June 29 after suffering a heart attack. He was 65.
Citing Davis' wife, Ruby Fleming-Davis, the site reported that a family memorial will take place in a few weeks, during which Davis' ashes will be scattered in the ocean; fans were asked to make memorial donations to the American Heart Association.
Davis left the regular cast of SG-1 in 2003 because of a medical condition that restricted his workload, but he made several guest appearances on the show and its spinoff, Stargate Atlantis.
A native of Missouri, Davis had a 26-year career that included many roles on TV series, notably Maj. Garland Briggs on Twin Peaks. He met SG-1 co-star Richard Dean Anderson on the set of MacGyver, on which he worked as a stunt double for actor Dana Elcar.
Davis' final Stargate appearance is in Stargate: Continuum, the upcoming straight-to-DVD movie. He will also appear in the films Vipers, Woodshop and Far Cry.
