Tom Felton, Meg Bellamy, Steve Pemberton and Reece Shearsmith on The One Show

Harry Potter star Tom Felton left viewers seriously confused during his appearance on The One Show as they failed to recognise him. Tom played Draco Malfoy in the Harry Potter franchise from its debut film Harry Potter and the Philosopher’s Stone in 2001 to the finale which came out 13 years ago.

During the episode of The One Show that aired on Wednesday 8 May, hosts Alex Jones and Jermaine Jenas welcomed Tom, now 36, to the sofa and viewers were shocked to see how much the child actor had changed. One said: “Omg, that is not Tom Felton on @BBCTheOneShow”.

Another viewer wrote: “Genuinely didn’t recognise Tom Felton on The One Show, makes me feel old lol”. While another added: “@TomFelton is really fit.”

Tom sat alongside The Crown actress Meg Bellamy and creators of Inside No.9, Steve Pemberton and Reece Shearsmith. After Alex introduced Tom, he went on to speak to the hosts about his new play, A Child Of Science, which is about the discovery of IVF in the UK.

He explained: “The character I’m playing is a geneticist who really was the starter but didn’t manage to go much further without introducing the lovely Gene Purdie and Doctor Who pioneered it, not overnight but over decades of research with hundreds of courageous women. It’s an incredible story which I knew very little about.”

Tom’s play, A Child Of Science, will be in theatres from June 5 – July 6 at the Bristol Old Vic. The synopsis reads: “Bruntwood Prize-winning writer Gareth Farr’s brilliant new play tells their pioneering story and those of the army of women from all over the UK whose immense bravery helped them achieve the impossible – to create human life in vitro.

“Faced with fierce criticism and hostility and hounded by the media for “playing God”, trials were kept largely under wraps. But their determination to give hope to the thousands of families struggling to conceive eventually led to one of the most remarkable medical breakthroughs of our time: the birth of a baby girl and the creation of IVF, a procedure which has supported the birth of over 12 million babies worldwide over the last 45 years.”
