It was said that KyotoAni hates Haruhi and its fans. But apparently they hate seyuu too:
Sankaku Complex links to an appearance Hirano made -- though I don't think the quote in the headline is a potentially misleading translatin. What she actually says is "yatteru hou yori miteru hou ga taihen da na to omoinagara..." which is roughly that she thinks that watching it was worse (tougher, harsher, or if you prefer, more awful) than making it.
She goes on to talk about the pressure of having to record the same episode eight times. (Remember, they re-animated each episode, so it would need to be re-recorded every time, not just the few changes.)
Hirano also notes that all of the cast was mystified when they heard they'd be doing the same episode, and that it was especially tough for Tomokazu Sugita, who plays Kyon, because he had some ad-lib moments.
She also thanks fans who stuck with the show past Endless Eight and says that it's nice to have escaped the arc.
Oh and yes, the Hitler. Also, check out the faces of Orion.
