Ledger, who passed away in January 2008, could have put his mind to anything, said Oldman, reported Contactmusic.
"To watch Heath was dazzling. He had a light around him. I don't know what it was. If he put his mind to anything, I think he could probably. He was thinking of directing," said Oldman.
The 54-year-old actor, who has just completed filming for the sequel, 'The Dark Knight Rises', said he has grown older and wiser on Hollywood politics.
"You have to have the acceptance of who you are, not worrying about what somebody over there is doing. All that insecurity, 'he's better looking', 'he's taller', 'he's better than me'. Thank God all of that has gone. You just go, I'm okay. Though awards definitely get you believing it for a while," he said.
