This is inaccurate, because fighting and bleeding were both removed in NHL 94. Secondly, the bleeding and fighting were in the game they were playing: NHLPA Hockey '93.
Visible crew/equipment: At the beginning when Jon Favreau is on the phone in his flat you can see the cameraman reflected in the window directly in front of him. (00:06:25)
Rob: Those guys are right. You're money.
Mike: Then why won't she call?
Rob: She won't call because you left. She's got her own life to deal with and that's in New York. She's a sweet girl and I love her to pieces, but fuck her, man. You got to get on with your life. You've got to let go of the past Mikey, and when you do, the future is beautiful.
