He leaped to fame as Harry Potter's nasty cousin, but the man in real life couldn't be more different.

Harry Melling has stayed in the acting game but he's moved from film to the stage as he debuts a new play Hands To God.

The 26-year-old is taking to London's West End 15 years after he portrayed the part of Dudley Dursley, and many will find it hard to recognise him all grown up.

He appeared on the Lorraine show today, and let's just say fans were shocked with his transformation.

Meanwhile, many have commented on his acting style, with The Evening Standard saying, "Melling, who's turning into one of the most interesting actors of his generation, is wonderful to watch."
