Before any confusion arises, let us clarify. It is not that on every Christmas, Shahrukh Khan sends a box of chocs to Aamir and this year he won't! But it definitely has everything to do with Christmas, King Khan and the Perfectionist Khan!
Since Aamir Khan's Ghajini is due for release on a Thursday (25th December), instead of the usual Friday, and because it is coming just two weeks after Shahrukh Khan's Rab Ne Bana Di Jodi, the distributors of Aditya Chopra's film are not willing to let go off the seventh day (Thursday) of the second week, at cinemas, where the film is booked for two weeks' fixed run. The reason being that Thursday the 25th is Christmas, when collections are expected to be bountiful because of the festival mood and holiday.
In other words, the distributors of RNBDJ are sure to insist on running their film for 14 days, and not 13 and so Ghajini would have to come in those cinemas on Friday, the 26th instead of Thursday.
However, things can take a Christmas spirit turn if King Khan is in a benevolent mood and asks his friend Aditya Chopra to yield some pre–booked screens to Aamir Khan's Ghajini!
