Those who have problems understanding Scots-accented dialogue spoken in Glasgow take heart. Subtitles are provided, although the practice becomes a bit droll when English swear words you can't mistake are also subtitled. You don't need a subtitle to translate what one can go do to oneself.

To play Liam, about to celebrate his 16th birthday, Loach cast Martin Compston, who never had any acting experience. He emerges very convincing as the troubled youth who scarcely realizes the danger he is in when his drug-dealing infringes on entrenched adult operators. But he has plenty of nerve, more than is good for him. Michelle Coulter, who play's Jean, Liam's mother, had never acted before either. This also was the first time on-camera for Annmarie Fulton, who portrays Chantelle, Liam's sister, although she had acting training. Chantelle is the one character who is able to achieve a measure of stability, and in some ways is a mom to Liam.

Liam's buddy Pinball (William Ruane) is another messed up teen. It is clear early on that he and Liam are headed for big trouble. Yet Liam's motivation is pure of heart as he nurtures the hope that by finding a place for his mother to live he can turn her life around. There is enough heartbreak in "Sweet Sixteen" for several Loach films.
