Rupert Grint reveals all about working with John Malkovich on new Poirot adaptation The ABC Murders

Harry Potter star Rupert Grint is a very long way from Hogwarts this Christmas as he stars in BBC1’s dark new adaptation of Agatha Christie’s The ABC Murders. In the three-part drama, John Malkovich plays Hercule Poirot, while Rupert plays Inspector Crome. Scotland Yard detective Crome gradually overcomes his hostility towards the Belgian sleuth to help him try to stop a twisted serial killer.

Rupert Grint tells TV Times about playing Inspector Crome in The ABC Murders…

TV Times: What’s Crome’s relationship like with Poirot?

Rupert Grint: ‘Playing someone with authority is new for me so it’s great! Crome has this deep insecurity about being over-promoted at a young age. There’s a lot of pressure on him with this case. There’s animosity with Poirot that warms as they get to know each other. They have different styles of sleuthing. Crome doesn’t have intuition, he jumps to conclusions, but Hercule becomes a mentor and he learns a lot. It’s an interesting dynamic.’

TVT: Is it intimidating clashing with John Malkovich?!

RG: “Yeah! I’ve been a huge fan of his for a long time and I remember the first scene we had clocking eyes because he’s a real presence, even when he’s not saying anything. I’ve enjoyed working with him, he’s a lovely guy. He’s brought something special to Poirot. It’s different but it feels right and like he’s been playing Poirot for years.”

TVT: Are you an Agatha Christie fan?

RG: “Murder is something I’ve definitely been fascinated with! I watch a lot of murder documentaries. I’ve never delved deep into the Christie novels though but I’m converted and I’d like to read more. This story feels unapologetically dark, brutal and bleak. That’s a fresh way of looking at Agatha Christie; it isn’t comfortable.”

TVT: Have you enjoyed the 1930s look?

RG: ‘Yes, my moustache is another layer to lose myself in and being on the smoky sets is atmospheric. I’ve still been recognised outside though but I don’t mind. I always get spells shouted at me!’

The ABC Murders airs on Boxing Day, Thursday 27 December and Friday 28 December at 9pm on BBC1
