The biggest star — a 10-metre-long, 6½-tonne bus that gives the show its title — barely made the first few performances, and has resulted in the production requiring huge theatres.
Hence getting kicked out for Miss Saigon, which requires a functioning helicopter more or less. In either case, when the 'star' is a prop or set piece your in trouble from the start. Plenty of work for me however, so keep up the huge sets kids.
