"If Les Mis is a success then Miss Saigon will be made into a film. It isn't confirmed at this point but there are many people sniffing around and offers coming in," Macintosh said in an interview.
The film of Les Miserables, starring Hugh Jackman, Anne Hathaway and Russell Crowe, will debut Christmas day.
In 2009 it was reported that "Precious" director Lee Daniels had Miss Saigon on his film wish list. Film producer Paula Wagner was also said to be working on a deal with Mackintosh at the time.
Schönberg and Boublil collaborated with Richard Maltby, Jr. on the 1989 musical Miss Saigon, which took inspiration from the Puccini opera Madama Butterfly. Set during the fall of Vietnam, the musical centers on an American G.I. and a young Vietnamese prostitute who fall in love against the backdrop of the war. When Saigon falls and the Americans pull out, the young woman is left behind.
