Recently, I made a trip to the Academy of Motion Picture Arts & Sciences building in Hollywood to scope out their exhibition of Bob Peak movie poster artwork. Not familiar with the name "Bob Peak?" Do you recall the posters for such films as Superman: The Movie, Camelot, Apocalypse Now, West Side Story, Every Which Way But Loose, In Like Flint, Rollerball, The Spy Who Loved Me, and the first five Star Trek motion pictures? Then you've seen Peak's amazing work.
Peak has been called the "father of the modern movie poster" for his brilliant designs and use of collage to depict scenes from the films. His use of color and especially light was second to none -- look at the energy in this image Peak created for Prince of the City: http://tinyurl.com/3ot7jam.
My only disappointment, if you could call it that, was I was expecting to see brush strokes or little smudges on the original artwork. Instead they were absolutely perfect pieces, almost like photographs (there were a few pencil roughs for some of the posters, and those were on slightly crinkled paper). I did find it amusing they had to touch up the Silverado poster. The large main figures are all on horseback, with the horses splashing in water, and there is brush spatter (imagine using a toothbrush to fleck specks of paint) that hit some of the smaller portraits higher up in the actual artwork. Those were touched up for the final poster printing.
If you can't make it out to Hollywood, please check out the Bob Peak website http://bobpeak.net/. You will be delighted and thrilled.
