It has come to light that Howard Stark is going to be in this movie - but he won't be the young version played by Dominic Cooper. John Slattery is reprising his role as Tony Stark's father from Iron Man 2, so we can only assume that he had some kind of relationship with an older character from this movie - most likely Michael Douglas' Hank Pym. So, what will Stark's role be? Will he have something to do with the development of Ant-Man's technology? If so, does Tony Stark know more about this than we realise? What exactly will Howard's role be in Ant-Man? We will have to wait until next year to find out.
