It seems the studio wanted even more time to develop the script, which had already been through numerous re-writes, which caused Singleton to leave. It isn't clear if new writers have been brought on to the project.
Singleton appeared to be the only person attached to the film, aside from writers Michael Brandt and Derek Haas (Wanted), as no casting has been announced, even as the film was set to be released on July 12, 2009. Fox has now set a release date of June 11, 2010 for the film, even though a replacement director hasn't been named.
We'll surely keep you posted on any and all The A-Team developments as soon as more information comes to light.
The A-Team was released June 11th, 2010 and stars Liam Neeson, Bradley Cooper, Jessica Biel, Quinton Jackson, Sharlto Copley, Patrick Wilson, Gerald McRaney, Henry Czerny. The film is directed by Joe Carnahan.
