Factual error: In the scene where Hobbes is talking to Reese in his cell, Reese talks to him in a foreign language. It's stated on at least two occasions that Reese is speaking Dutch. He isn't - he's speaking German.
Continuity mistake: When Hobbs (D. Washington) enters his brother Art's bedroom, soon to find him dead, he opens the door without closing it. After grieving for a short time he stands at the door, now closed, as he gathers himself as to what he just saw.
Suggested correction: You can hear the door close by itself as soon as he enters the room.
Suggested correction: It's Dutch. "Wie de bal kaatst." Just what Reese said. "What goes around..."
