Filming began October 31, 2000. From the onset of filming, difficulties with the studio slowed the film's development and caused a rift between the director and Universal Pictures, as executives were unhappy with the film's pacing, emphasis on small scale action sequences, and the general relationship between themselves and Liman, who was suspicious of direct studio involvement. A number of reshoots and rewrites late in development, plus scheduling problems, delayed the film from its original release target date of September 2001 to June 2002 and took it $8,000,000 over budget from the initial budget of $60 million; screenwriter Tony Gilroy faxed elements of screenplay rewrites almost throughout the entire duration of filming. A particular point of contention with regard to the original Gilroy script were the scenes set in the farmhouse near the film's conclusion. Liman and Matt Damon fought to keep the scenes in the film after they were excised in a third-act rewrite that was insisted upon by the studio. Liman and Damon argued that, though the scenes were low key, they were integral to the audience's understanding of the Bourne character and the film's central themes. The farmhouse sequence consequently went through many rewrites from its original incarnation before its inclusion in the final product.
