Stewart picked up the Best Fantasy Actress honour at the event, held to applaud all things sci-fi, and The Twilight Saga: Eclipse was named Best Fantasy Movie. It was also a big night for True Blood, which picked up Best TV Show from number one fan Marilyn Manson.
The drama also claimed the Holy Sh--! Scene of the Year accolade for its much-publicised head-twisting sex encounter, while True Blood stars Alexander Skarsgard and Anna Paquin were named Best Horror Actor and Actress.
Other prizes went to Zombieland (Best Horror Movie), Ryan Reynolds (Top Anticipated Movie for Green Lantern), Mickey Rourke (Best Villain for Iron Man 2) and moviemaker Christopher Nolan (Most Mind-Bending Film for Inception).
Halle Berry and Megan Fox were among the early presenters but even they failed to steal the highlight of the night - as tributes to Back to The Future and Ghostbusters hit the stage.
Funnyman David Spade stepped out of Back to The Future's time-travelling DeLorean, which was driven onstage at the Greek to a standing ovation and then he introduced the film's stars Michael J. Fox and Christopher Lloyd, who were given another rapturous welcome.
Later, Bill Murray took to the stage in his Ghostbusters costume to accept Zombieland's Best Horror Movie prize.
Other highlights included a guest appearance from Sir Anthony Hopkins, who gave the audience a preview of his upcoming exorcism movie The Rite.
Horror icon Wes Craven then joined Scream 4 castmates Emma Roberts, David Arquette and Neve Campbell to present a world-premiere teaser for the latest film in the Scream franchise.
There was even a special moment for Sigourney Weaver, who was handed a lifetime achievement award and rolled onto the stage in an egg-like structure similar to the pods in Avatar.
The very special awards show was rounded off by a performance from M.I.A.
Against all odds a lightweight Broadway musical made up of ABBA songs and an innocuous storyline has become a worldwide phenomenon still running and selling out wherever it plays. Now it has been given the big-screen treatment filmed on location in the Greek Isles. The story basically remains the same (and oddly similar to the 1969 Gina Lollobrigida comedy Buona Sera Mrs. Campbell) about a young girl Sophie (Amanda Seyfried) on the eve of her wedding. She has decided to find out who her real father and so she invites all three of her mother Donna’s (Meryl Streep) ex-loves to the wedding. With the arrival of Sam (Pierce Brosnan) Bill (Stellan Skarsgard) and Harry (Colin Firth) all hell breaks loose as Donna must not only deal with the impending nuptials but also the re-emergence into her life of three very different--and now older former flames. Helping her through the ordeal are her two best friends Rosie (Julie Walters) and the seductive Tanya (Christine Baranski). All this of course is just an excuse to break out into song every five minute with all of the major ABBA hits used to move the story along--or just stop it dead in its tracks. Either way it’s a toe-tapping experience apart from every other film we’ve seen this summer. With a cast not exactly known for their musical skills this version of Mamma Mia is indeed a roll of the dice which has paid great dividends for the most part. With few exceptions (we’ll get to Pierce’s warbling in a moment) the entire cast shines and delivers--beginning with Streep who is simply a force of nature. She’s sensational and can she ever sing! Her big 11-o’clock-number “The Winner Takes It All ” which she belts out against the stunning scenery of Scopelos (where much of the movie was filmed) will remind you of Barbra Streisand’s triumphant anthem “Don’t Rain On My Parade” from Funny Girl. Streep is the real deal--Hollywood’s real hidden singing and dancing queen. You just have to wonder why she hasn’t gotten more musical opportunities in film. Baranski and Walters are delightful sidekicks and each belt out their own numbers in style. Seyfried (HBO’s Big Love) is a great discovery a charmer who keeps the film grounded and unveils a natural singing voice. As for the guys both Skarsgard and Firth get through their limited vocals with seeming ease and have a great camaraderie as does Brosnan--acting-wise at least. His musical numbers while on key exhibit a voice that probably isn’t going to top the charts anytime soon but you have to give him credit for swinging er singing for the fences. Despite his iffy pipes he and Streep display such great chemistry it would be nice to see them re-team somewhere down the line. It’s not often Hollywood offers a Broadway show’s creative team the chance to repeat their stage success but give credit to Universal for bringing in the original director Phyllida Lloyd writer Catherine Johnson and producer Judy Craymer. Consider the fact that they are all over 50--just like three of their key female stars--and you have a situation in which youth-obsessed Hollywood has reversed course--all for the good. Although Mamma Mia is not shot with the kind of razzamatazz style a Rob Marshall (Chicago) might have brought Lloyd’s feature film debut hits the mark with zeal enthusiasm and the gift of fun. It’s a good-time movie with a refreshing lack of pretense and makes it one of the most purely entertaining musical events ever to hit a motion picture screen. Lloyd has re-captured on film the unabashed joy of the theatrical experience and staged it in one of the most beautiful places on earth. If it’s a little disconcerting to see all these older stars belting out a Swedish pop group’s greatest hits it’s also probably just what audiences living in these troubled times need. Our guess is you’ll want to line up and see it again the minute it ends.
