I’ve found an article about the movie. From what I could get with the help of online translators, if you buy a pre-sale movie ticket, it comes with a school calendar (it’s limited edition, one pic with Arakawa’s original drawing).

There's an animage scan (June 2011 issue) that Chan_Chanz on livejournal has kindly shared. I think it has some sort of interview on it or something? I think it's something pertaining to what Michiyo- posted above (the interview with the VAs) but if I'm wrong this post can be moved to somewhere suitable later. XP)
