Re: How characters received their names
. . . It's related to the disclaimer you always see, "The characters in this show are fictitious and any resemblance to any individual, living or dead, is purely coincidental." It's a hedge against lawsuits for defamation in case someone thinks a fictional character is based on them and portraying them in a bad light, or otherwise undermining their ability to earn a livelihood.
Those disclaimers seem pretty silly in an obvious film à clef
like The Rose
or The Greek Tycoon
. Of course, a different standard applies in the case of portraying public figures, whether or not the names have been changed to protect the guilty.
