I wonder why people in the US are so conscious about sticking completely to the script. I read an interview somewhere with Damon Herriman, an Aussie actor who got a guest role in Cold Case, and I remember he said that on Aussie shows, actors are generally allowed to ad-lib a bit more.
I think it's more of a matter of individual writer, director or producer preference, as well as whether the ad libbed lines are actually funny or good enough that the writer/director/producer like them and don't mind them being added to their script. It could also be affected by things like time contraints and budget. Making a movie or TV show is I think more expensive here, and if the actors are allowed to just ad lib whenever they please, it can result in scened having to be reshot, or if they keep the ad libbed line, depending on how it changes, it could necessitate changes being made in other scenes as well, possibly scenes that have already been shot, or result in certain other things having to be re-written. Anything that would result in the necessity of re-doing a scene too many times, or cause production to slow down would cost money and be discouraged.
I have heard that Thomas Hayden Church is notorious for little ad-libs and changing up his lines a lot, and Ben Afflack is known to try to do it, too, according to Kevin Smith. Thomas Hayden Church ad libbed a line that went something like, "Do you have a degree from Verm-Tech Institute?" or something similar in the movie Over The Hedge, and the writers loved it so much that they put it in the finished script. In his case it is probably just his sense of humor or because he gets bored easily. In Ben Afflack's case, it could be a combination of being an Oscar winning writer (along Matt Damon for Good Will Hunting) and working on a Kevin Smith film, he may not do this on the set of other films. Because Kevin Smith likes to use his friends when he makes a movie, it's probably a lot like making a student film in high school or college and there is a lot of playing around and joking going on behind the scenes, so they don't take things too seriously.
