Baltimore-based Betsy Royall Casting will handle the extras casting for My One and Only. a movie starring Renee Zellweger that is slated to begin shooting in Baltimore beginning May 27.

Anyone interested in working as an extra on the film should send a recent photo of him- or herself (it doesn't have to be a professional portrait or headshot, just a "true representation" of what you look like) to Betsy Royall Casting, C.S.A., 6247 Falls Road, Baltimore, 21209

Include with the photo a 3x5 index card, stapled to the photo's back, in the upper left corner, containing the following information: Name, union or non-union (union number, if applicable), age, height, weight, pants size, shirt size, dress size, phone number and email address.

Also indicate whether you'd be comfortable getting a 1950s-style haircut, whether you'd be able to work weekdays, how far you live from downtown Baltimore, and any special skills you have (do you dance or play a musical instrument)

Finally, mention it if you own a car from the 1940s or 1950s.

No phone calls, please.

My One and Only is expected to use about 750 extras, all in non-speaking roles. Although many will be union members (about 75 a day), non-union extras also will be used.

In addition, Royall will be looking for musicians and dancers, in their 20s, 30s and 40s, for scenes involving a big-band orchestra.

My One and Only is based loosely on the memoirs of actor George Hamilton. Zellweger's character, based on his mother, is a glamorous socialite scouring the East Coast for a wealthy husband to support her and her son.
