In the 1950's, Jerry Lee is performing that 'devil's music', and quite good at it. We see him go to Sam Phillips, the man who made Elvis a star. Will he be the next Elvis? He might very well be that talented. Phillips is very impressed, and his record becomes a hit.
Once Elvis goes into the army, Lewis has his chance to become as big as the King, if not bigger. What may have been his downfall, if this movie is accurate, is his marriage to his second cousin Myra. The English do not approve, and Americans aren't much more receptive.
Dennis Quaid does a great job, although it is apparently Lewis himself doing the singing. But Quaid pounds that piano and behaves wildly and shows a lot of passion and energy. I did enjoy the music, even though I usually like my music softer. It's amazing Lewis' music was banned by radio stations, because his songs get played on the station where I listen to Frank Sinatra, Perry Como and Nat King Cole.
Winona Ryder is a delight, especially when Myra goes shopping after the wedding. Steve Allen looks surprisingly young playing himself, and he seems to be having a good time.
Elvis appears briefly several times, played by Michael St. Gerard, who portrayed the King in a 1990 TV bio. Elvis doesn't say much, but he does look the part. In one scene he and a girl are in bed together watching Lewis perform on TV, and the girl seems to want to do 'a whole lotta shaking'. Footage of others watching Lewis is shown (though they are probably watching something else). Included are a shocked Ward and June Cleaver.
'Patricia' by Perez Prado seems appropriate for the scene where Jerry Lee and Myra wonder whether to tell Myra's parents. The organ has the whimsical, playful quality that is such a big part of Myra's character, the trumpet section reflects Lewis' wild streak, and the trombones sound like Myra's father probably will after he gets the news.
While there were negatives in Lewis' life, this movie doesn't really make these look as bad as it could have. I found the movie entertaining as a whole.
