When 26/04/11 09:45 <<<<<<<<<< this means it's in the morning!!
Where Leicester Square, Odeon
AYBG's edit: Thanks to the poster below, and one on the Thor discussion thread, this is confirmed for Leicester Square, not Leicester. If you got a ticket it will be valid for the screening (though obviously there's none in Leicestershire), but my advice is to email showfilmfirst as the others have done, and print their reply in case of any difficulty on the night.
Thanks ledrex on mse
