Ant-Man's love interest may be played by Evangeline Lilly. Lilly who has most recently appeared as the elf Tauriel in The Hobbit: The Desolation of Smaug, is rumoured to be in early talks with Marvel, according to Variety.

The 34-year-old actress could be, should talks prove successful and media outlets accurate, starring as the daughter of Hank Pym and the love interest of Scott Lang/Ant-Man in the 2015 Marvel film adaptation of their comic-book classic. Paul Rudd, best known for his comedic roles in Friends and Anchorman, is set to star as Ant-Man, a superhero who is able to change his size. Michael Douglas will be involved in the project and Michael Peña (Gangster Squad) is also rumoured to have been cast in the film. 

In comic book lore, there have been three Ant-Men: the first being Hank Pym, a scientist who first discovers how to alter his size using a substance he creates. Pym, in the upcoming adaptation, will be played by Michael Douglas. Although Pym did not have a daughter in the comics (strangely Lang did) this may be director and co-writer Edgar Wright's new different approach to the film. 

The second Ant-Man is Scott Lang, a thief who stole Pym's suit containing the aforementioned size altering material. Finally Eric O'Grady has no connection to the previous two but, as a S.H.I.E.L.D. agent, discovers the ant-suit in the storage and proceeds to use it for his own dastardly deeds. 

Little of the plot has been revealed other than the names of the two main characters and it is unknown who Lilly is being considered to play. 

The film is currently in pre-production and production is due to begin in April. Ant-Man is due to be released in the US on 17th July 2015.
