who was ludlow's wife having an affair with ? That never got explained but I did have a feeling it might have been captain wander. I kept waiting up to the end for Captain Wander to confess this to ludlow up until ludlow killed him. Who else thought something similar?
On the DVD I watched they had a bonus feature with deleted scenes. In one of those scenes (in the final confrontation at his house) Captain Wander mentions that it was him who was sleeping with Ludlow's wife and dropping her at the hospital, leaving her to die.
So you're right. However it did make sense to me to leave this out of the final cut, since Wander is already corrupt enough anyway. No need to make him the one most evil guy out there or the source of all the *beep* up stuff that's going on in Ludlow's life.
It's been a little while since I've seen the film, but I don't remember any talk about Ludlow's wife cheating on him. When did this happen (or when was it talked about)?
If I'm not mistaken, it's alluded to more than once in the movie. It comes up when Ludlow sees the medical examiner after the shooting of his old partner: they would not test his late wife for traces of DNA when her body came in. Ludlow's wife died of an aneurysm or some other condition which might have been treated if she would have received medical attention ASAP. Instead she had been dropped off on the hospital's doorway, unconscious and laying there until somebody found her. Ludlow wanted to get her tested for DNA, so he could get his revenge on whomever left her to die on the street. They didn't check her.
I also think it comes up when we see Ludlow at Wander's home (after Washington being shot?), Wander tries to convince him that he needs to get over all this.
It's been a while since I've seen the film as well, but I think it's more alluded to than really explained in detail.
They didn't do tests because Wander ordered (someone) to ensure no tests were done. The tests could have implicated whomever dumped her, which simply would not be in Wander's best interest.
Life is tough, but it's tougher when you're stupid.
