Corrected entry: "Allegra Cole"'s name was likely chosen as a homage to Allegra Coleman, a fictional celebrity supermodel (much like Allegra Cole) invented by writer Martha Sherrill for the purposes of a hoax magazine article. Model Ali Larter portrayed the imaginary model in Sherrill's feature which appeared in Esquire (November 1996).

Correction: The fact that you said "was likely chosen" makes this an opinion of yours and not actual movie trivia.
