Alex DeLarge (McDowell), a violent juvenile in the near future, is caught after a number of brutal rapes and murders. While imprisoned, he submits to a controversial experiment to make criminals ill at the mildest suggestion of violence or conflict or anything sexual. Now Alex's victims want to welcome him back into society with the same enthusiasm Alex had always exhibited when performing his crimes.
Trivia: According to actor Malcolm McDowell, director Stanley Kubrick was concerned that the Droog attack on F. Alexander and his wife would become just another dark, cruel and violent scene in a movie that was already full of dark, cruel and violent scenes. Kubrick wanted the Alexander home invasion to stand out as genuinely horrifying, but he was at a creative impasse. After Kubrick shut down production for several days to ponder the problem, he thought of Alex dancing during the attack. Malcolm McDowell suggested dancing (and singing) along to "Singin' in the Rain," as it was the only song to which he knew all the words.Charles Austin Miller
