Ant-Man release date is just a couple of months after the Avengers 2: Age of Ultron premieres this May, and there are some plot rumors suggesting that the incredible 'Hulk' will appear in Marvel Comic's latest entry to its line of superhero flicks.

This speculation rooted from 'Hulk' actor Mark Ruffalo's recent posts on his tumblr and Facebook accounts promoting Ant-Man release, hinting the Marvel fans that he could be in it?

Meanwhile, the latest news regarding the film's cast is the addition of Judy Greer. The 'Arrested Development' star plays the character of Maggie, the ex-wife to career criminal Scott Lang (Paul Rudd) turned superhero, Ant-Man whom she shares a daughter with, named Cassie.

Scott and Cassie's father-daughter relationship is staged in the recently released teaser trailer and Greer mentioned during the TCA Press Tour just this week that this sub-storyline will be the heart of the movie itself.

She said, "Ant-Man is my first comic hero that I've really researched and fallen for. I also think the Ant-Man origin story that we tell in our movies is really beautiful and I think there's something really real about a man trying to better himself for his family."

This may seem the kind of plot that the new superhero shares with other costumed protagonists, i.e. Iron Man, to exist in the Marvel Comic Universe, albeit, he being a dad is what could draw a difference in terms of perspective per se.

One generic ingredient included in the recipe of Marvel movies is Comedy and Greer revealed that is true with Ant-Man. 

"I haven't seen it yet but there was a lot of comedy on set and we did a lot of comedic improv. I don't know what will end up in the movie, but yeah."

The original creative success of Iron Man is attributed to the comedic improv playing an important part in the whole movie and the likes of Rudd alongside Greer have really been great at.

The official poster for the Ant-Man movie is already out revealing lead actor Paul Rudd suiting up for his role. Release date is slated to hit the theatres in the United States on July 17, 2015.
