Two episodes focus on Mr. Director as an adevesary to Yakko, Wakko, and Dot: Hello Nice Warners and Hearts of Twilight. He has also made minor appearances in other episodes, including Taming Of The Screwy (as one of Dot's pets), The Warner's 65th Anniversary Special, and Macbeth. He also appears briefly in the made-for-video Wakko's Wish film, when King Salizar sends them into "The Cave Of Your Worst Nightmares."
He tends to use faux-Yiddish nonsense words such as "Flamiel" and "Freunlaven" while speaking erratically. Typically, he keeps a calm and collected demeanor; however, while acting and occasionally while speaking to others, he speaks in an crazed, exaggerated manner. While speaking in this manner, Mr. Director is able to even annoy Yakko, Wakko, and Dot (whom he calls "puppy children"), a feat which few others can accomplish.
- "Take the word 'animal.' Transpose the letters 'n' and 'm' and you get 'aminal.' That, in a nutshell, is comedy."
