Kind hearted Robert De Niro has spent time in jail offering help to prison convicts.
De Niro met actor Danny Trejo on the set of Michael Mann's 1995 crime epic Heat, and he was intrigued to hear the Hollywood tough guy - who is a reformed criminal - regularly gives motivational talks to prison inmates.
And Trejo was quick invite the Hollywood legend along.
He says, "I always ask movie stars to come out to jails with me and talk.
"That guy (De Niro) actually showed up. He went out to jail where everybody was hardcore. And he came and talked. On his own. I was so sure he wouldn't turn up, I didn't put his name on the list. Then all of a sudden we got a call from the front desk, saying, 'We got Robert De Niro down here!'"
