Biggest Loser Audition Tips from Casting Director Allison Kaz

UPDATE: Biggest Loser Casting Season 11

allison kaz biggest loserSince the inception of Biggest Loser in 2004, one person has been behind the scenes selecting the individuals who would go on to weigh-in on that infamous scale. Allison Kaz is the casting director for Biggest Loser, a job she’s had for going on nine seasons. When you speak with her, you can hear her enthusiasm for the job and the role she plays in helping these individuals move forward in their quest for health, and often times happiness.

I had the opportunity to speak with Allison during the summer casting for Biggest Loser 9. The show is currently doing a 15-city casting tour, including Chicago, Detroit, Atlanta, Oklahoma City and for the first time, San Antonio. When asked if there’s a science to the cities selected for open casting calls, Allison replied that they “try to change it up a bit” each season. But the city selection is based on a number of factors. She says they go where the obesity trends are, and pay attention to reports regarding the fattest cities or fattest states in America.

Allison even addressed the question that many of our Canadian readers often ask – “what about Canada?” Due to the legalities of the show involving a competition and prize money, she explained, it’s only possible now to cast legal U.S. residents.

For those of you preparing to attend one of the open casting calls this summer, Allison shares some key advice that could help you make it beyond the crowded lines.biggest loser trainers

  • “Say everything you want to say.” You have about five minutes in front of the casting crew. Don’t walk away wishing you’d said something else.
  • They’re looking for personality, charisma, uniquity.
  • Know your story! Know who you are, what your motivation is, and why you want to do this. And make that perfectly clear to the casting crew.

Allison also had a couple of tips for things not to do at the Biggest Loser casting calls. Remember, they want to see the real you.

  • Do not share your sob story.
  • Do not wear costumes.
  • Do not try to be something you’re not.

Whether you’re there to earn a spot on the show or to support a loved one, she says the open casting calls can be a “rewarding experience.” Hopefuls form a bond and camaraderie while waiting in line that often goes beyond the audition and creates life-long friendships.

She also advises that the casting calls are not necessary, and that submitting a video and application is just as likely to earn you a spot on the show. Allison confirms that they do watch every video they receive, and people have been casted solely based on their video submisison.

I have now attended two casting calls and I thought that everything was more than kosher. I think people need to realize that this is first entertainment and the by product is a fresh start. Casting calls are cattle calls no matter if it's TV, film or theater - there are always going to be tons of people auditioning for the same role.

Fair or not, the casting director knows what (s)he is looking for and they are well trained and can detect in the first few seconds of meeting you. So if you are going to "shine" you have to make it happen the first second you're there. Maybe a tape is the way to go?

I like BJ also attended the casting call in Portland Oregon. I too thought it poorly organized. We were told specifically not to be there before 3 hours before doors opened. This was definitely not the case!! No one monitored this. There were far more people than expected and I don't feel we were given 1/2 a chance to make an impression.

I attended the Audition in Portland Oregon on the 28th. It seemed to be terribly managed timewise as over 2,000 people where only given about 8-seconds to speak.

I was one of those, we where asked our name,age,occupation, weight and how much we wanted to lose and we where out the door. it was an assembly line of people given 8 seconds. :(

I attended casting call in OKC. Ten people were assigned to a table and there was only 10 minutes for everyone combined. The first three or four to speak got a very respectable amount of time to speak but the closer it got to the end of the table, the less time we each got. Unfortunately, I was toward the end and didn't have much time beyond my name, age, weight. I was so disappointed. I know it is hard to work with such a large number of hopefuls but we got nothing close to 5 minutes to "shine".

Thank you for the information. Headed to OKC on Saturday. As excited as I am .... I am nervous. I want this so badly I can hardly focus on anything else. My video has been posted to YouTube so I have gotten that part accomplished.

The Fat Chick

I went to an open casting call for season 8. The turnout was much higher than expected, and the people near the back of the line didn't really get a chance to interview as they were just trying to get through everyone... and they told us the best way to audition is through a video submission.

Is there a big difference between what casting directors are looking for in person compared to an audition video? The discussion is about whether or not a couple of audition videos have enough "sob story" in them. Does it really matter?
