FILM CHOICES

The Belles Of St Trinian’s, 2.30pm, BBC2

THE first of the original trio of comedies (Blue Murder and Pure Hell follow on Wednesday and Thursday) about the uncontrollable schoolgirls created by artist Ronald Searle. Headmistress Miss Fritton (Alastair Sim) isn’t in charge of much at all.

The Mechanic, 11pm, Ch5

JASON STATHAM (pictured) is on typically macho form as an experienced assassin who takes the son of a murdered colleague under his wing to teach him the tricks of his trade — and exact revenge on the men who set up the hit. A brisk remake of the 1972 Charles Bronson/Michael Winner original.
