YES! This is pretty awesome! Hellsing finally gets a TV Deal on something that's not the 5am slot on Starz lol.
As far as content goes, they will need to edit a bit, but not much. Seras' Flashback in episode VII will be getting edited as will maybe a BIT of the blood and Gore, but I think they'll be fine with most of it.
I'm not worried about that as much as I'm worried about them editing it for time actually.
Hellsing was produced as an OVA Series and as such, no standard was set for episode length, so you get wild variations on how long each episode is. the breakdown, in order is like this:
OVA I: 51 Min, OVA II: 43 Min, OVA III: 47 Min, OVA IV: 56 Min, OVA V: 44 Min, OVA VI: 42 Min, OVA VII: 45 Min, OVA VIII: 49 Min, OVA X: 1 Hour, 8 Min.
Broadcast standard these days is 43-45 min per episode so the rest can be filled up with commercials. OVA II and V-VII should be able to air without modification, but pretty much every other episode is going to need to cut content for time, and this series already kindof has an issue with that. The first 4 episodes have slight pacing issues where they kinda tried to stuff a tad too much of the manga into it. While the episodes are good, the pacing is a bit breakneck and there's very little room to remove stuff and have the story still fully make sense…
Then of course, while minor edits will be needed across the board, OVAs I, IV, and ESPECIALLY X will need to have heavy amounts of content removed. OVA X will need around 25 minutes of content removed to fit into a 43-45 min time slot....
Hell, if they made it a hardline cut down to 43 minutes per episode for every episode, with JUST the amount of content cut from OVAs I, IV, and X... you could make one whole extra episode... and you'd then need to trim 3 minutes off that extra episode you just created...
Maybe they can edit all of the episodes together into one huge chunk and then cut the huge chunks back down into 11 43 minute chunks for broadcast?
