Boy loves girl but has a fling with her mum in this classic comedy drama that turned Dustin Hoffman into a sex symbol
"Mrs Robinson, you're trying to seduce me... aren't you?" muttered young college graduate Benjamin (Hoffman) to middle-aged Mrs Robinson (Bancroft). And thus one of the most famous seduction scenes in the movies was born.
As well as the blistering script, it's the cast that make Mike Nichols' film positively sing. Hoffman was perfectly cast (legend has it that Robert Redford was originally offered the role) as the jaw-droppingly naive Benjamin. Katherine Ross is demure as Elaine, while Bancroft - who is only six years older than Hoffman in real life - got the part of a lifetime, and knew exactly what to do with it (and has not been bettered by the actresses who have attempted the role in the theatre version).
