Thor: The Dark World and Two Different "Free Loki" Campaigns

Loki Marvel Studios Panel

Marvel Studios rolled out their "Free Loki" viral campaign today, with a #freelokisweeps hashtag on Twitter where fans can register for a signed t-shirt from actor Tom Hiddleston.

Last night, they teased it as "#freeloki" but as it turns out, that's taken.

A user on the Twitter handle @free_loki has been using the #freeloki hashtag for some time to petition Marvel for a feature film based on Thor's villainous brother, the standout star of Thor and Marvel's The Avengers.

An online petition supporting the Loki movie has over 9,000 signatures on it. You can check it out at the link at left.
