That’s right – not even in theaters until next July 17, 2015, the mid and end credit scenes for the movie has already been unveiled (well, what will happen in it, at least). According to comicbookmovie.com:
In the mid-credits scene for Ant-Man, “Hank Pym (Michael Douglas) gives the Wasp costume with wings to Hope Van Dyne (Evangeline Lilly)” and “Hank explains to Hope what happened to Hope’s mother Janet Van Dyne.” As for the post-credits scene, “Captain America (Chris Evans) and Falcon (Anthony Mackie) have located The Winter Soldier (Sebastian Stan) to a remote location where The Winter Soldier is tied up.” Falcon asks Cap, “Should I call Stark?” He replied “No,” before Falcon says, “I know who to call,” referring to Ant-Man. Falcon appears in key scenes in the movie.
Adding credibility to the above descriptions, the finalized Ant-Man cast list confirms that Anthony Mackie is definitely in the movie while Chris Evans and Sebastian Stan have “uncredited” roles. Evidently, they all, including Paul Rudd, return in Captain America: Civil War.
