LOS ANGELES (Hollywood Reporter) - The world of "Thor" is filling up. Jaimie Alexander and Colm Feore are coming aboard the Marvel Studios adaptation of its comic book featuring the Norse god of thunder.
Kenneth Branagh is directing the feature.
Alexander and Feore join Chris Hemsworth, already cast as Thor; Tom Hiddleston, who plays Loki, the god of mischief who serves as the movie's villain; and Natalie Portman, as Thor's human love, Jane Foster.
The movie's story centers on Thor, a powerful but arrogant warrior whose reckless actions reignite an ancient war. As punishment, Thor is cast down to Earth and forced to live among humans. Once here, he learns what it takes to be a true hero when the most dangerous villain of his world sends dark forces of Asgard to invade Earth.
In the epic fantasy, Alexander will play Sif, a skilled Asgardian warrior who can hold her own against any man. She also is one of Thor's loves.
Feore's character, a villain, is shrouded in mystery; the studio isn't even sending the actors the script.
Alexander, best known for "Kyle XY," also has been cast as a pharmaceutical sales rep in "Love and Other Drugs," starring Anne Hathaway and Jake Gyllenhaal.
Feore had recent stints on "24" and "The Listener." He appears in "The Trotsky," which debuted at the Toronto International Film Festival.
