Just a few days ago, we brought you the news that Ewan McGregor (Haywire, The Impossible) was in negotiations to join the cast of Bryan Singer‘s forthcoming fantasy film, Jack the Giant Killer as the leader of the king’s royal guard who helps in fighting off the giants.

Now, Deadline reports that Eleanor Tomlinson (Alice in Wonderland, Styria) has joined the cast as Isabella, “the princess who runs away from the kingdom and is kidnapped by the giants. Before that happens, she runs into Jack, the son of a farmer and makes a strong enough impression that he leads a mission into the land of the giants to get her back“.

Tomlinson joins McGregor, Nicholas Hoult, Stanley Tucci (Captain America: The First Avenger) who was cast as the movie’s villain, Roderick, the adviser to the king with shady plans to overtake the land of Cloister, and the combo of Bill Nighy (Harry Potter and the Deathly Hallows: Part 2) and John Kassir (The Gunrunner Billy Kane) who will each portray one of two heads of Fallon, the two-headed leader of the giants.

Jack the Giant Killer is slated to hit theaters in 2012.
