I absolutely adore Elvis Presley. He is my favourite singer of all time. However, I'm not a huge fan of his films and neither was he. Many consider "Jailhouse Rock" to be his best movie, but I definitely disagree. It feels very slow and dull at times. It seems the script has created some good, believable characters, and the casting was chosen well, because the acting was realistic. In fact it's so rare that an Elvis movie has such a good cast. Yet after the characterisation, the plot is quite weak and repetitive. Elvis's character Vince Everett isn't particularly likeable as a person. In fact he's quite horrid, but I guess that helps make it more interesting in what is otherwise a rather boring film.
The songs for the movie are all absolutely fantastic. However the actual recording quality of those songs is rather poor, as there is not enough bass on any of them. Listening to them with headphones on would hurt your ears something chronic. Yet the "Jailhouse Rock" sequence is without a doubt amazing. Choreographed by Alex Romero and Elvis himself, that two minute section of the film is a masterpiece, and remains a contender for the first music video.
It is about time RCA remastered the songs properly, as they already have done with "Jailhouse Rock". After all, the song "Baby I Don't Care" would be one of my favourite Elvis songs, if it wasn't for the poor quality of the sound. And it's got nothing to do with "how old" these songs are. Elvis was recording music as early as 1954, and some of those records sound a hundred times better!
