Dom DeLuise's character, Melvin P. Thorpe is based on the real newsman, Marvin Zindler (b. 1921, d. 7/29/07) who brought down the real Chicken Ranch. The incident where the sheriff snatches the wig off Thorpe's head and holds it high really happened between the Fayette county sheriff and Zindler. Zindler also pioneered "rat and roach" reports about restaurant cleanliness ("Slime in the Ice Machine!"),
The exterior of the Chicken Ranch was erected on the Universal lot where the Bates house from Psycho (1960) originally stood. The Bates house was moved to a more permanent location when filming began on Psycho II (1983). The set is still up on the Universal lot in 2011 and was used in "The Ghost Whisperer".
Marvin Zindler, on which Melvin P. Thorpe is based, liked the play but didn't like the film. Zindler said that his crusade against the Chicken Ranch has been taken out of context. He wasn't trying to get it closed down because of the prostitution, but because of the Ranch's reported ties to organized crime and other shady business dealings.
The original Broadway production of "The Best Little Whorehouse in Texas" opened at the 46th Street Theater on June 19, 1978 and ran for 1584 performances.

The scenes shot in the Austin, Texas Capitol Building were filmed from October 6-9, 1981. The bulk of the footage was shot at night in order to keep from inconveniencing workers and visitors - though many workers lost their parking spaces that week to make room for the studio's 18 wheelers.
Dolly Parton's hit I Will Always Love you was actually composed and released a decade before The Best Little Whorehouse In Texas. However her songs A Cowboy's Ways and A Gamble Either Way were written specifically for Whorehouse, despite being released on her personal albums instead of appearing in the film.
