With just over two months left until Teenage Mutant Ninja Turtles hits theaters, new concept art has surfaced from an upcoming book that gives us a look at the villainous Shredder (William Fichtner) and Splinter (Danny Woodburn). Fans got their first look at Splinter in a TV spot from April, while Shredder has been glimpsed in the trailer and in toy form. The latest scans, which also feature Megan Fox as April O'Neill and the turtles Leonardo (Pete Ploszek), Donatello (Jeremy Howard), Raphael (Alan Ritchson) and Michelangelo (Noel Fisher), are from the upcoming book Teenage Mutant Ninja Turtles: The Ultimate Visual History, which will be published on June 24 from Insight Editions. Take a look at these new images before the heroes in a half-shell hit theaters on August 8.
