It is one of those movies, when you expect it to be bad or mediocre but you end up having a great time.
It's tells the story of Liberace, a well known and famous pianist and entertainer, he lived a life of success and sexual perversion, he was known for his costumes and his candelabra (he came up with an idea of setting a candelabra above his piano), the movie didn't focus on his art, instead, it focused on his relationship with Scott Thorson (played by Matt Damon), and that's actually convenient because Scott Co-wrote this movie, the movie starts with Scott, he's a bisexual good looking guy who wants to be a veterinarian, and his friend introduced him to Liberace once, so Liberace offered Scott to come work for him as his assistant, and things evolve into a gay relationship.
I think the gay relationship wasn't the most interesting part about the movie, how scott evolved was more interesting, he was very shy at first, it obvious that he never tried a gay relationship before, he used to shiver when Liberace touch him, so you get to see Scott change, from that guy, to a jealous person, with a "California Diet", drug addictions and plastic surgeries, you get to see him abandoned his entire life, dreams and people who raised him just to become somebody's boyfriend, an idea that he completely rejected at first, but a life of glory, cars and gold made him forget what he really wants.
I wasn't familiar with Liberace before watching this movie, i actually never even heard about him, so i didn't think that this movie is going to be interesting, but it did surprise me, specially the performances, as usual, Matt Damon performance was incredible, even more incredible was Michael Douglas, he had the look, the walk, even the voice, you can watch interviews with the real Liberace to confirm, the movie production design was really interesting, they used actual items, furniture, specially made costumes, Jewelry's and many things were used by Liberace.
I think it's fair to mention that the movie somehow was more about Scott than Liberace, i mean, they didn't focus on his music, i think they're were only two maybe three scenes of Liberace playing the piano, which is why the movie title is "behind the candelabra" not "Liberace" i was actually worried on the way Steven Soderbergh will interpret this story, i don't like this director, and i thought that he was going to glorify a life style of perversion (drugs, homosexuality, plastic surgeries, ect.), but somehow he stayed on the line and kept a Biography pattern and did a very good job, if i have to criticize, i think he should have included more drama but it was good nonetheless.
Overall, it's a good, enjoyable movie, with great performances, great music and a valid message.
