The Walking Dead actor Andrew Lincoln, who played Rick Grimes on the zombie series, has commented on how he believes the AMC show “over-egged the omelette” at one point. Speaking to Empire, Lincoln said the infamous and gory death of Steven Yeun’s Glenn was when the show might have gone too far.

On the show (and in the comics) Glenn is brutally murdered by Jeffrey Dean Morgan’s Negan, with Negan ferociously bludgeoning Glenn to death with a barb-wire-wrapped baseball bat.

“I do still think [Glenn’s death] might have been when we over-egged the omelette,” he said. “Maybe it was lingering too much.”

Lincoln said filming that sequence was among the “most intense” experiences he had making the show. He also reminded people that Morgan is, of course, nothing like Negan–he called Morgan “one of the nicest guys you’re ever going to meet.” Lincoln also said Morgan deserves praise for filming Negan’s monologue sequence on his very first day shooting The Walking Dead.

“Everybody was on their knees and weeping when they weren’t on camera,” Lincoln said. “[Morgan] came over and went, ‘Is this normal?’ I went, ‘Yeah, everybody just keeps going.’ It was an extraordinary night.”

Lincoln left The Walking Dead during Season 9, but came back for the series The Ones Who Live. The latest Walking Dead series, The Walking Dead: Daryl Dixon – The Book of Carol Season 2, premieres this September.
