FastCo. Design takes a look into the ever-shifting Warner Bros. logo, which has undergone many, many changes in the last 90 years. From their timeless shield look to some 70s-era rebranding by design legend Saul Bass, the iconic movie studio has solidified around their classic logo style in the last ten years. But they’ve also let directors put their own spin on the logo to fit the mood of their movie. It’s resulted in over 200 variations in the last ten years alone, and added a whole new dimension to a classic icon of the movie world.
