We all know Titans Will Clash. But now Potter Will Clash too. In 3-D. Thanks to Titan's positive testing, the final two instalments of Rowling's wizard franchise will be bumped into third dimension as well - something fast becoming standard practise for big summer blockbusters.

Warners Bros haven't officially confirmed this, but rumours have been rife (over at MarketSaw) of their tentpole releases being converted to cash cows (at a cost of $5 million apiece). Knocking Titan's release date back by two weeks is a direct casualty, but Potter has time to recover from the blow: he'll continue to uncover the Deathly Hallows in November this year and July of next. Now he just needs some snazzy glasses - Luna's already got some.
