The characters are an entertaining group
of misfits,
of particular note is central protagonist and narrator Renton (Ewan McGregor), a young man with aspirations
of stability, and
of happiness in his life, but who is utterly unable to survive without «one more hit», the violent and psychotic Begbie (Robert Carlyle), who refuses to take heroin but
makes up for not doing drugs by «doing people» instead, and the childlike Spud (Ewan Bremner), the
innocent fool of the group, and the most vulnerable to peer pressure.
