Japanese American actor Tohoru Masamune portrayed the Shredder in "Teenage Mutant Ninja Turtles". Initially, William Fichtner was intended to portray a Caucasian version of the Shredder, with the anglicized real name of Eric Sacks, instead of Oroku Saki. This idea was abandoned late in production in favor of featuring a Shredder of authentic Japanese ancestry, and the film went through re-shoots to change Fichtner's character of Sacks into being the Shredder's student. The change came too late to alter the film's Nintendo 3DS tie-in video game, and Sacks remains the Shredder in it. In contrast to much of the brand's history, Sacks, not Shredder, is the character connected to the Turtles' origins, having created them alongside April O'Neil's father; the Shredder (never referred to with any name other than his codename) has no connection to Splinter or the Turtles, and while he is shown to have scars on his face, it is not revealed how he suffered them.
