The actor will take on an unspecified role in Peyton Reed's Marvel Studios project, reported Deadline.
He will appear in the Paul Rudd-starring superhero film alongside Michael Douglas, Evangeline Lilly, Corey Stoll, Michael Pena and Patrick Wilson.
Dastmalchian was most recently seen in 'Prisoners'. He won the Courage in Filmmaking Award at the 2014 SXSW Film Festival for Animals, which he wrote and starred in.
Reed signed on as director of the film after the surprise exit of Edgar Wright in May.
Wright had been attached to the project since 2006.
'Ant-Man' will be released on July 17, 2015.
