While speaking at the Santa Barbara International Film Festival, Johnny spoke about Leo and reminisced about the long days on the film set.
"It was a hard time for me, that film, for some reason. I don't know why. I tortured him. I really did," he told Entertainment Weekly.
Of the much younger Leo, Johnny said, "He was always talking about these videos games, you know? I told you it was kind of a dark period. 'No, I will not give you a drag of my cigarette while you hide from your mother again, Leo.'"
Johnny was 30 years old while they filmed the movie. Leo was 19 years old and earned rave reviews for his role as disabled teen Arnie Grape.
Now, though, he actually couldn't be prouder of Leo, who is the odds-on favorite to win an Oscar for "The Revenant."
"I'd say the absolute truth is that I respect Leo a lot," Johnny said of Leo, who he hasn't worked with since the 1993 film. "He worked really hard on that film and spent a lot of time researching. He came to set and he was ready to work hard and all his ducks were in a row."
In anticipation of his probable Oscar win, everyone is trying to get aboard the Leo train right now.
