On the last thing he said to Paul: "'If I do die, let them know what kind of brother I've been to you.' I've played that over in my head countless times. That's the last time I ever saw him."
On finishing the movie for him: "There was fear. Could I finish playing Dom with such a broken heart? . . . I thought what Paul would really want me to do was finish it. So that's what I did."
On his first day back on set: "I'm supposed to be in killer mode . . . I went through three boxes of tissues, and I felt so bad. I felt so embarrassed. I had always been the kind of actor that other actors respect. I was just failing so hard. My nose was running and my eyes were tearing. I had to walk off set to try to get all the fluids out. I couldn't contain my emotion, and thus it became the toughest film I ever had to shoot."
