There was a pretty funny mistake in episode 4 that I spotted when watching on ABC.com.
At the start of minute 37 in the episode, Sam and Harvey Keitel's character are sitting on the hood of a car and talking, after they. had just found the dead hooker by the water. As they are talking, there is a tall building in the backround that very clearly has the "Verizon" symbol on it. Kinda strange considering that it's supposed to be 1973. It's located right over Sam's left shoulder. Pretty funny. Huge mistake on the studio's part. Wonder if they know about it already.
