Patrick Wilson, Kevin Weisman and Matt Gerald will no longer star in Marvel's upcoming Ant-Man movie.

Production on the film, which stars Paul Rudd in the title role, was first disrupted when director Edgar Wright exited the project in May, and while he has since been replaced by Peyton Reed, the delays have caused scheduling conflicts for Wilson, according to Deadline.

The characters set to be played by Weisman and Gerald are reportedly no longer in the script following a re-write.

Michael Douglas, Evangeline Lilly and Corey Stoll will also star in Ant-Man with the film slated for release in July 2015.
