"A new behind-the-scenes video from the Harry Potter Wizard&amp;#039;s Collection has debuted online. In the 90-second preview, released through Sugarscape, a young Daniel Radcliffe and Tom Felton are seen playfully squabbling on Quidditch brooms as they prepare to film a scene from Harry Potter and the Chamber of Secrets.  Director Chris Columbus also discusses the teething problems with effects in the early movies, saying: &amp;quot;The visual effects in the first film were done towards the end of shooting. So we didn&amp;#039;t have enough time to really get them to where we wanted them to be. &amp;quot;In the second film I wanted the visual effects to be much better than the first, so what we did is we shot those sequences first. It really enabled us to spend five, six extra months on Quidditch.&amp;quot; The Wizard&amp;#039;s Collection features 37 hours of special bonus material and more than four hours of unseen content. Also included are extended versions of Columbus&amp;#039;s two Harry Potter instalments Philosopher&amp;#039;s Stone and Chamber of Secrets. The Harry Potter Wizard&amp;#039;s Collection is due to arrive on September 10 and will cost \u00C2\u00A3259.99/$499.99.
