This is a poster for a movie called According to Greta. The poster uses the time honoured tradition of quirky indie movies and has gone with a notepad hand-drawn motif so I can't help but assume that it is indeed quirky and indie. It's probably got "jokes that mask a hidden sadness" and "tells truths that we don't want to admit". etc.
It also stars Hilary Duff. Say wha...?
I like to imagine there is a scene where Ellen Burstyn slaps Hilary Duff to the tune of some twee guitar-strumming indie rock band.
Please note that I have no idea what this movie is and have never heard of it before and, thus, am making complete and utter assumptions about it and its quality. There's a very possibly chance that According to Greta is actually quite good, but I think we can all safely assume it will be no Raise Your Voice.
