Steven Yeun goes from 'Walking Dead' zombies to intergalactic robots in 'Voltron'

Spoiler alert: Do not read if you haven't watched the current season of "The Walking Dead." Steven Yeun has gone from "The Walking Dead" to an animated life. The actor, who was horribly dispatched in the seventh-season opener of the AMC drama, can currently be seen in "Voltron: Legendary Defender," flying a red metallic lion into space as he helps save the universe. Yeun had already taken on the role of the mysterious Keith, the orphaned paladin (pilot) of the red lion, in Netflix's reboot of the '80s cartoon series, aware of the brutal end that was going to befall Glenn Rhee, his "Walking Dead" character. "It's all a little bittersweet," says Yeun. "I feel great, though. It feels good to have completed something."
