Thanks to an apparent slip-up by the British Board of Film Classification, we have an early look at the special features for the Blu-ray release of Thor: The Dark World, which include an exclusive look at Captain America: The Winter Soldier and, most intriguing, a new "Marvel One-Shot" called "All Hail the King."

Considering the title, and the ending of The Dark World, speculation naturally leans toward a Loki short, which might go a long way in placating the nearly 50,000 Tom Hiddleston fans who signed an online petition asking Marvel to produce a solo film starring the trickster god.

And, hey, why not? Marvel seems to know what fans want -- and what they want is more Loki -- going so far as to add last-minute scenes to the Thor sequel to give Hiddleston more screen time. Marvel Studios Co-President Louis D’Esposito, who directs the "One-Shots," revealed in July that he had tried to develop a Loki one-shot, but it would've been too cost-prohibitive (the studio instead shot "Agent Carter"). However, it's entirely possible the 13-minute short was part of those Thor reshoots.

Following the leak of the special features list, Marvel released a trailer for the Thor: The Dark World Blu-ray, which arrives Feb. 25.
