The role may be a bit of a SPOILER so if you don’t want to know more, please turn back now.
Russo has signed on to play Thor’s mother, Frigga, reports.
Frigga’s role in the film may differ from her few appearances in the “Thor” comic. In Marvel’s continuity, Frigga is the step-mother of both Thor and Loki — not their actual mother. Thor is the son of Odin and the Earth goddess Gaea while Loki is adopted by Odin after his Frost Giant parents are slain in battle.
