When is a design a homage to an iconic previous design, and when is it just lazy theft? I have no idea if the new Keanu Reeves movie, Siberia, mirrors or echoes content from the 1969 Robert Redford skiing drama. However, the latest poster certainly bears a resemblance.
Maybe design firm Gravillis Inc., are simply fans, and wanted to create a modern take on one of very few great 'floating head' designs (not to mention superb use of negative space). I find it difficult, however, to believe this a coincidence.
