Benefit to raise money for Studios Streetmosphere performer
Donna Charles, best known for portraying Rosie the Cleaning Lady for many years as one of the popular Streetmosphere characters at the Disney-MGM Studios, suffered a stroke three months ago, but hopes to return to work in the next week or so. Her fellow cast members have organized an after-hours benefit show at the Theater of the Stars at the Studios (normally home to Beauty and the Beast Live on Stage) to help her out. Every dollar raised will go to Donna to help defray costs for medical expenses and loss of work.
An amazing line-up of Streetmosphere characters, current and retired, will be performing, as well as some of her former colleagues from her days at the Adventurer's Club. (Please note that this will not be a typical "Disney" show, as this is an unofficial event focused on Donna.) Since the show is not being sponsored by Disney, there will be no official mention of it anywhere, and only those who are already aware of it will have any knowledge that it is occurring.
A benefit will be held on August 11 for Donna Charles, best known as Rosie the Cleaning Lady. Photo courtesy of event organizers.
A Stella Night, For "Rosie" will take place on Friday, August 11, at 9 p.m. Doors will open between 8:00 and 8:30. As this is a special event, park admission is not required. A guest relations host will greet guests attending this event at the far right of the main gate of the Studios, near the ATM. Guests will be directed through a backstage area directly to the Theater of the Stars, During this walk to the Theater, Guests will be interacting with Streetmosphere as they are directed to this "Red Carpet" event.
There is a suggested $10-per-person donation at the door. A silent auction will also be held, featuring items not available to the public from all of the Equity stage shows within the Disney-MGM Studios.
Donna Charles began working at Walt Disney World in 1982, doing trunk shows at EPCOT Center with the SAK Theater. She was selected to be a member of the original cast of the Adventurer's Club at Pleasure Island, creating the role of the club's maid. She was later asked to move to the Disney-MGM Studios to become part of what became known as Streetmosphere. She has created several Streetmosphere characters, including Rosie, who is now one of the most requested characters at the Studios.
