Lennie James suffered night terrors after starring in 'The Walking Dead'.
The 59-year-old actor played Morgan Jones in the post-apocalyptic horror drama and in its spin-off, 'Fear the Walking Dead' - but Lennie struggled to leave the TV show behind when he wasn't on set.
Asked if he learned anything about survival from being on 'The Walking Dead', Lennie told the Guardian newspaper: "One of the byproducts of being in the zombie world for as long as I was, was I started having very vivid and lucid dreams. I would quite often wake up shouting in the midst of a night terror, waking the house and making it difficult for my wife to sleep next to me.
"Someone suggested CBD oil, and it works. So I’d take that into a dystopia."
Lennie is a good friend of Jason Isaacs, star of 'The White Lotus', and the actor has admitted to being a huge fan of the TV series, too.
Lennie also insisted that he's "not as good" as his showbiz pal.
He said: "I hadn’t seen the first two seasons – I’m not very good at watching obnoxious characters on screen – but one of my best mates, Jason Isaacs, is in the latest season. I started watching it, and it hooked me.
"Jas’s performance was fantastic. We’ve known each other since just after drama school. I’m not as good as him, but I try."
The actor quit the UK for Los Angeles before he turned 40.
Asked why he decided to relocate to America, Lennie replied: "I had done at least one lead in a television show and a number of leads on stage. I was being told that I should be satisfied with that because that was a definition of success over here for someone who – as I took it – looked like me.
"I just wasn’t willing to let somebody else decide what my ambition should be. I wanted to challenge myself as an actor, to see what was possible. I landed there when I was a relative grown-up and I seemed to arrive at the right time; it went stupidly well for me immediately."
