Frank Skinner looks for the man behind the icon in this intimate portrait of his hero Muhammad Ali, who died a year ago next Saturday.

In Ali's Kentucky hometown, Frank meets his brother and confidante Rahman, and in Pennsylvania he visits the compound where Ali trained for 1974's Rumble in the Jungle.

There's also a chat with an Oxfordshire bare-knuckle boxer who became one of The Greatest's closest friends.
