Did you even bother to watch at least thirty seconds of the thing from the start, or did you fast-forward through all of it? Right at the beginning, before Year One even starts, a message pops up on the bottom of the screen, telling you to stay tuned after the credits for the bonus features. It's essentially a documentary/series of interviews about Batman.
hmmm, the reason i skipped forward is because i've seen the film once and read the comic numerous times i was just interested in the bonus features... so when i did skip towards the end around an hourish into it, it was at the very last scene
so how do you access the interviews towards the end? is it like a button you press or is it 5 minutes long?
No problem. As soon as the credits for Year One finish, it automatically goes into the documentary/interviews. Also, I believe the documentary has its own set of credits too, so don't accidentally get the credits confused if you're fast-forwarding through it all.
