Continuity mistake: Duke is wearing an extra shirt, and his hair is longer then it was, despite continuing the scene from the end of season 2.
Episode #1.1 - S1-E1
Continuity mistake: Luther goes to see Zoe and the house is an end terrace with a red door. Later he goes back and it's mid terrace with a black door.
Suggested correction: No, I don't think this is an error. I think the house with the red door is Luther and Zoe's marital home and the house with the black door is Mark's home.
That's what I thought, but how did he know where Mark lived?
I think it's a mistake because Riply is outside keeping watch on Zoe's house. At that point, Luther didn't know who Mark was, so how could he know where he lives?

Continuity mistake: When the bomb under the bus is being defused, it's counting down and beeping once every second. We see the timer at 0:45, then cut to the face of the woman defusing it - counting the beeps when we cut back it should be on 0:45, but it's jumped up to 1:06. Camera pans down to her face, then back to the bomb, and it's now on 0:43, but going by the beeps it should be on 0:36. We cut away again for 5 more beeps, cut back and the bomb's only just ticking onto 0:41.
