Fantastic film, can't wait to see it again next week.
Morrissey isn't mentioned at all, a bit of a jarring omission. I saw the film twice so far (once at the film festival, and a few weeks ago at a free screening RMIT were having; they didn't check student cards or anything), and may do so again; or just get the DVD with the outtakes which are mentioned in the dialogue.
Manchester aside, I can't wait to see the film because it stars Steve Coogan as Tony Wilson. Coogan was previously brilliant as Alan Partrige, host of Knowing Me, Knowing You (Ah-ha):

There's a competition to win free tickets and CDs and junk at http://www.uktv.com.au/ , although their entry form seems to be b0rken. There's a 1900 number though, if you're feeling rich and lucky (O_o)
The omission of Morrissey didn't worry me to be honest... as he was never on Factory, his presence would have been fairly peripheral anyway, although it might have been nice to have the story about him writing to Wilson. On balance, better off without him.
From memory, I don't think Morrissey gets mentioned in the film at all! There are PLENTY of other cameos to keep anybody happy, and if you don't catch them all, there's a section where they explain who everyone is.
