The Majestic Theatre at Six Flags Over Texas was closed Tuesday night after a small fire started on the outside of the building. The Arlington Fire Department responded to a call about 8:20 p.m. There were no patrons inside the theater, which had just finished with the last showing, said Sandra Daniels, park spokeswoman. Daniels said performers were in the dressing room but were evacuated by fire officals. The building sustained minimal damage, confined to the exterior of the building, she said.
