Labor disputes have blocked Marvel Entertainment's goal of releasing two films or maybe just one, for next year. According to The Hollywood Reporter, during Tuesday's earnings call with analysts, chairman David Maisel said "Regarding 2009, we have been obviously affected by the labor situation in Hollywood," referencing the recently ended writers strike and "the uncertainty caused by the upcoming expiration of the actors agreements at the end of June."

Maisel didn't say which character might star in a 2009 movie, if there is to be one, though he did say that films featuring Ant-Man, Captain America, Thor and the Avengers all are in development.

Marvel plans to release Iron Man in theaters on May 2nd and then The Incredible Hulk on June 13th.
