Yeah. I was going to say that. It will do as A:IW Friday till Noon but after that shall start leading as A:IW had more % ticket sold in pre-sales so less room in evening, so I think it may just hit ¥400mn.
Depend on the distributor. Like for South Indian films they report the previews on Thursday itself but now distributor make exceptions there as well. Like Baahubali 2 they reported previews with Friday.
Mostly because a bigger opening day is better PR. That's my 2 cents.
