Played with in The Read Through in which the Harry Potter characters are essentially actors playing themselves in various pieces of fan fiction, but are nothing like the characters they portray. For one, Dobby is actually over six feet tall and has a deep voice, but he can ACT short.
The door opened again allowing Draco Malfoy and Dobby Elf into the Read Through room.
"Greetings Fellow Thespians!" Dobby called in a deep cultured baritone that would make James Earl Jones green with envy. "I do hope everyone is ready for today's foray into the theater of the mind."
Molly and Ginny joined them all sitting around the table. Behind Dobby and Draco came several interns carrying copies of the day's script and started placing them at each place around the table, along with pens and highlighters.
One of the interns stopped in front of Dobby. "Mr. Elf, sir, I've been a fan of the series since the beginning, you've always been my favorite character."
"Well thank you…" Dobby eyed the intern's nametag, "Stephen, I am but a humble player among this great ensemble cast, playing my part as best I can."
"Oh, you're the best sir… but I was wondering, you don't look anything like your character."
"Ah, I see, you expected an emaciated two foot tall golem with huge eyes did you?"
"Yes sir Mr. Elf, I never would have recognized you. How do you do it?"
"How else Stephen?" Dobby struck a dramatic pose "By ACTING!"
Stephen the Intern blinked, standing before him was the Dobby from the books and movies, two foot tall, huge eyes, clad in a threadbare pillowcase, he blinked again and Mr. Elf was back, six foot four clad in a Thousand Pound Saville Road suit, the picture of the Shakespearian actor. "That's amazing Mr. Elf, I had no idea someone could 'act' short."
"Only after years of training young Stephen. Fetch me a cup of tea and half a bagel with cream cheese would you? Good Lad."
The intern scampered off and Dobby took his seat at the table. Draco looked up from the script in front of him. "You insufferable ham."
