Beam Me Up, Scotty!: In a minor way. Ron's surprised statement, "Boy... That escalated quickly!" is often misquoted as a deadpan "Well, that escalated quickly..." instead.
California Doubling: Much of the film was shot in Los Angeles and Glendale, on backlot sets designed to look like '70s San Diego.
Defictionalization: You can buy Sex Panther in real life. Fortunately it's a fairly normal aftershave rather than the horror described in the film.
Deleted Scene: So many that they were able to make a whole other movie out of them.
Development Hell: The sequel. Paramount had expressed interest then lost it then renewed interest...then stepped off again...and finally greenlit the project come 2012, over seven years after the first movie.
What Could Have Been: During the production, a lot of alternate takes were produced and a lot of plotlines were cut, including a major plotline about an inept terrorist organization known as "The Alarm Clock". So many, in fact, that instead of being included in a Director's Cut version, they were edited together to produce a Direct-to-DVD sequel Wake Up, Ron Burgundy: The Lost Movie.
The original producer was, of all people, Paul Thomas Anderson. In fact, he instigated the film! After director Mc Kay and Ferrell wrote a different screenplay and couldn't get it greenlit, Anderson said that they should make a new script and whatever they made, he'd produce it. For one reason or another, he couldn't produce after all.
