The first thing I should say is this isn't an extended version of the film! It's a re-release of the film with more indepth extras. So if you don't already own it this is the version to buy!
The storyline if you don't already known follows the battle of vampires against the lycans (werewolves). The lycans are growing in number and the vampires become interested in why they would be searching for a human. Soon the battle commences again with the human at the centre of it.
Personally I think this is a great action film, definitely not a horror. It is up there along with he likes of The Matrix and Blade. All the films have a similar look and feel to them, partly as they all have comic book backgrounds? This is no bad thing as they are all very entertaining films. Full of action, great fight scenes, special effects, cool sound tracks, almost identical wardrobe dept (full length black leather jackets) and good storylines. This is the 1st in a trilogy that could better the other two, with Evolution on DVD soon. This does make it as a good film in it's own right, as well part of a trilogy. This is a well made film that has had a lot of thought, time and energy put in to making it. The idea of vampires having a war against werewolves is a great basis for a series of action films, I can't wait to see the last two!
The extras are all very indepth and cover all aspects of the film and are generally between 10-20 minutes each. Designing Underworld looks at the ideas for the locations, costumes, characters with some detailed concept art drawings. The vampires are very much the higher class, with the mansion, fancy cars and clothes. The Lycans are very much an underground movement with a rough, street feel. The look of Underworld covers the directors vision of how he wanted the film to look. The feel is very dark, with little colour, high contrast so the scenes are almost monochrome. Most of this is done post production digitally to get the right look. The making of Underworld covers finding the right location (Budapest), some of the stunt work, brief interviews with the main actors. There are TV spots, outtakes and a storyboard comparison for a few scenes.
The visual effects covers the make up, cgi scenes, models and weapons used in the film were done. Amazing to find out just how much is cgi you might have thought was real! The creature effects mainly covers the look of the vampires and how the werewolves look was designed and suits made. A lot of work goes in to making and moving one werewolf! The stunt feature shows Kate and the other actors training for their fight scenes, using weapons and wire work. There is also a sort of montage (sights and sounds), a music video. One of the most interesting features is a 5 part Fang Vs Fiction, which covers a lot about the history of vampires and werewolves. How the stories originated and evolved over time, a real bonus. Overall a great modern, cool action film with tons of extras!! 9/10
