Hamm, 43, who appeared alongside Radcliffe in 'A Young Doctor's Notebook', said his former co-star could indulge in a life of luxury to a much greater extent than he has so far, reported Daily Express.
"I think he is massively talented. For the majority of his teens he was the most famous person in the world, in the eyes of 13 to 18 year olds, but he has handled it all with a grace that is enviable. He could buy a castle in the Highlands and be done with it!," Hamm said.
