Hasn't it always been that date for the UK and Ireland?
No, it was planned for a release on the 23rd, and now they pushed it back 3 days.
Normally movies are released on a friday in the UK, not on the monday after the friday.
So now they have 3 more days for post-production.
Well, I suppose you can't release it before you've had the premiere. Still has the whiff of some difficulty fixing the date / place / attendees for that and then having to adjust to suit. Doubt they'll achieve much over one weekend. You might be right, but alternatively you might be assuming a major problem when it's more an administrative bodge-up.
