*In the movie Harry Potter and the Order of Phoenix, The Ministry of Magic atrium represents the largest set ever built for the Harry Potter films, at over 200-feet long, 120-feet wide and 30-feet high. It took more than 30,000 tiles to cover it, all of which had to be individually placed. Onscreen, the atrium will appear even bigger through the use of visual effects.

*Luna Lovegood is a somewhat quirky personality, who is unfazed by what anyone else thinks of her.  The character is making her debut in Harry Potter and the Order of the Phoenix, just as the young actress playing her, Evanna Lynch, is making her acting debut in the coveted role. Luna’s unique qualities made the part one of the most challenging to cast. Casting director Fiona Weir and the filmmakers met dozens of contenders, but none were quite what they had visualised for Luna, so they decided to hold an open call. More than 15,000 young hopefuls from all over the U.K lined the blocks, standing for hours and hours for their chance to audition.  

*Bringing Hagrid’s half-brother Grawp a 16-ft-tall giant to the screen involved a combination of design, motion capture, visual effects and the talents of an actor named Tony Maudsley. Tony Maudsley really became the part and imbued every movement with reason and rationale so, although the final character is more of a visual effect, Tony gave him a heart and soul. Creature and Make-Up Effects Designer Nick Dudman reveals that they did build a full-size head for Grawp to “act” opposite the actors on the set, as well as to provide a 3D model for the visual effects team to scan into the computer.

*‘The Hall of Prophecy’ is the first-ever completely computer-generated set in a Harry Potter film.
