12.Alex Vause from Orange Is the New Blackdidn't originally exist. Creator Jenji Kohan created the character for Laura Prepon after she auditioned for Piper.
13.Arizona Robbins was never meant to be a character on Grey's Anatomy. Shonda Rhimes wrote the part for Jessica Capshaw after she auditioned for another role.
14.Cliff Clavin was originally not a character on Cheers — in fact, John Ratzenberger persuaded the creators to write a role for him after he auditioned for Norm.
15.And finally, Freaks and Geeksdidn't have specific characters in mind when casting began. The characters we love today were only finalized after the cast was in place, meaning the show could've been completely different.
