Is this the docu that was on Channel Five a couple of years ago?
The scene I remember the most was when Donal asked Dominick's brother if he had killed anyone and he couldn't deny it.
Then we hear he'd been murdered later on.
It's that one-hour documentary, fleshed out to 1hr 37 (there's more about his brother's death and funeral, and it seems to me more about his fat, spotty underling who ends up bricking it at the funeral as he's over-reached himself with some proper gangsters).
Some scenes from the original are cut but included as extras.
