It was one of those movies that just seemed to be on all the time when I was growing up, and as a result, I think I internalized a lot of its imagery without really understanding any of its meaning. By the time I was an 18-year-old freshman in film school and sitting through Mike Nichol's film cut-by-cut in a lecture, the damage had already been done - Mrs. Robinson had already managed to influence me. Not that I'm a cradle-robbing alcoholic (at least, not yet), but certainly, style-wise, my entire fashion aesthetic seems almost unconciously modelled after Anne Bancroft in that film. The leopard print, the sunglasses, the big brown hair with the golden highlight at the crown. I remember as a kid just thinking that her look was the coolest, and I've never really gotten over it.
So I went online and I tried to find a photo gallery from the film, so that I could demonstrate what I'm on about here, but there isn't much. Instead, take a look at this page from NPR; they've got tons of audio features (including a report by Don Lee on the making of the film and interviews with Buck Henry, Mike Nichols and Dustin Hoffman) and a video clip from the film, of Benjamin's first encounter with Mrs. Robinson. The New York Times has more, including movie trailers and a short, career-spanning slide show.
