This Friday sees the release of "Hansel & Gretel: Witch Hunters "starring Jeremy Renner and Gemma Arterton as the fairy tale brother/sister duo. The film shot in March 2011 (before Renner filmed either "The Avengers" or "The Bourne Legacy"), and was originally set to be released in March 2012, before Paramount pushed it back ten months to its current slot in the January wastelands. But 'Hansel & Gretel' is hardly the only case of a long-delayed film making it to theaters in 2013. For instance, "Gangster Squad" was pushed back from September 2012 to January 11th after the Aurora shootings, though it would have been a horrible film whatever time of year it was released. And the two are set to be followed by a fairly staggering twenty-five films from major studios that have already been pushed back somewhere between five and thirteen months, many of them accompanied by serious production troubles and well-publicized reshoots.
