Discovering movie goofs in HD

[Blu-Ron]

Now that we are re-watching movies we loved in HD. Did you ever find really bad goofs that you can now catch in HD?
Confused yet?
Let me give you an example:
Halloween (1978) Remember the scene when Michael escapes from the hospital? That nurse chick is alone in the car and Michael's hand smashes the drivers side window. You can clearly see a wrench taped to his hand (added strengh to smash the fake glass, I guess). I always knew of this wrench but it was quite a shock to see it that clearly. Cause ya can't really catch stuff like that with VHS.
