"The author says Scorsese was in the wacko in the movie "Taxi." However, that was Robert Deniro."

But Scorsese does have a cameo in 'Taxi Driver', he plays a fare that Deniro's character picks up. As I recall he has only one or two minor lines and is mostly seen in Deniro's rear view mirror. (I may be wrong on the details, as I have not seen the movie in many years, but it is Scorsese in the back of the cab)."
Thanks for the clarification. I guess it would be fair then to say Scorsese's character was also a wacko, as was deniro's, as was Harvey Keitels, as was Jody Fosters, as was the guy who got his hand blown off, as was...
