#robertdeniro ‘s Mohawk from #taxidriver was not actually real, it's currently on display at the Museum of Moving Images in New York. Paul Schrader, the screenwriter of #taxidriver commented on the hairstyle saying: "Scorsese and DeNiro interviewed an ex-Green Beret who told them if a Special Force member felt he was going to die, he would shave his head into a Mohawk as a warning to his fellow soldiers." In the film, #travisbickle is a socially dysfunctional, paranoid war veteran that drives a taxi in New York to occupy his insomnia.
