Larry King, the 78-year-old former CNN anchor, failed to show up for a scheduled appearance at the Banff World Media Festival, according to The Hollywood Reporter.

The festival noted that King was unable to travel to the Rockies, but did not indicate whether his withdrawal was health-related, the story says.

The planned appearance by King was described as a headlining appearance, with King scheduled to receive a lifetime achievement award, the piece adds.

Previous recipients of the award include Ed Asner and William Shatner, the story notes.
