I am going to take this information with a grain of salt and I suggest you do as well for the fact that the place I got this information from digitalspy, did not site their source. Here is what they say that John Turturro says regarding a sequel to the cult classic 'The Big Lebowski'.
"The Big Lebowski was a great movie. We hope to make a sequel. I can't talk about it, but it comes down to Jesus in the jumpsuit."
Personally I don't think this movie needs a sequel. There is really no point. The first film should be the one and only. I loved the characters, but unless the Coen Brothers come back to do it then I am 100% out. What do you think?
