Harris Dickinson has admitted the idea of playing John Lennon is "frightening". He told the Sunday Times' Culture magazine: “It felt frightening because of the magnitude of the character — this icon. He said: “I’ve probably already said too much.”But Harris did reveal there is "of course" a WhatsApp group for him and his three cast mates but refused to reveal its name. I’m just a wimp.”The actor is still not sure how he will tackle the role. Asked how he will play Lennon, he said: "I actually don’t know.”
