During filming in 2002, 'Matthew Perry' spent some time in rehab due to an addiction to prescription painkillers. Production was slowed, but the filmmakers focused on filming scenes without Perry in them during his absence.
Many of the locations featured in the movie are actual locations found in Dallas Texas (e.g., the Texas Club, Reunion Arena, Dallas City Hall.) However, the stainless steel building of the "Moore Company" in the movie is actually the Dallas Federal Reserve Bank (K-11) which is located in the cultural district of Dallas.
The hotel concierge is played by Mike Judge who is a last minute addition to the film. According to Reggie Hudlin the original actor fell ill and was unable to appear in the movie, so he phoned Mike Judge who agreed to play the part.
