A youtuber made some English subs for the Saekano movie using a camrip over a month ago. I asked if they could provide the subs so that others can work on them. I received the subs as a .srt file but as I had trouble opening them in Aegisub, I've converted it into .ass. I'm not too sure about the quality of the subs, but they'll definitely require editing and timing fixes for use on BDs. I'd do it, but I'm an amateur when it comes to timing, and only know elementary-level Japanese. If anyone wants to try and use the subs as a base to make something better, go ahead.
