For Warwick Burton; Re: Taxi Driver
 
See the following:
 
Les Keyser, _Martin Scorsese_.  New York, Twayne Publishers, 1992.
Although factually incorrect in some places, it still has some
interesting things to say about the film and its director.
 
_Schrader on Schrader & Other Writings_.  Edited by Kevin Jackson.  London:
 Faber
and Faber, 1990. 115-120.
 
_Scorsese on Scorsese_.  Edited by David Thompson and Ian Christie.
London: Faber and Faber, 1989.  51-67.
 
Hope this helps,
 
Cheers,
 
Marty.
