It looks like the Avengers will need to assemble one last time before the May 1, 2015, release of “Avengers: Age of Ultron.” New reports claim that director Joss Whedon has called most of the cast back to film reshoots on the movie at Pinewood Studios in London.

According to a report from Daily Mail, Chris Hemsworth (Thor), Robert Downey Jr. (Iron Man), Mark Ruffalo (The Hulk), Jeremy Renner (Hawkeye), Paul Bettany (The Vision), Scarlett Johansson (Black Widow) and, most interestingly of all, Tom Hiddleston (Loki) are all returning to film additional scenes. According to the tabloid, the hope is that inviting the characters back will help ramp up the action in the highly anticipated superhero sequel.

While reshoots aren’t uncommon for feature films, especially major blockbusters on the scale of “The Avengers,” what’s most interesting about this news is the fact that Hiddleston will be filming more scenes in the movie. Previously, Whedon claimed that he would not include Loki in the second “Avengers.” A few weeks ago, however, Idris Elba let it slip that both he and Hiddleston would reprise their roles as Heimdall and Loki, respectively.

Hiddleston's character Loki is a villain that is beloved by fans of the franchise. He first brought the character to life co-starring alongside Hemsworth in “Thor” (and its sequel). In addition, he played the main villain in the first "Avengers." It’s unclear what role Loki will have in the upcoming film, but it’s clear his role will now be expanded in reshoots. So far, the only relic of Loki's character that's appeared in previews is his iconic staff from the first film.

It’s also worth mentioning that absent from the list of actors returning for reshoots is Chris Evans (Captain America). The super soldier apparently got everything he needed done when the film wrapped principal photography back in August. There’s no real way to infer anything about the film’s plot based on who is and isn’t returning for reshoots, but it’s possible fans will see less Captain America in “Age of Ultron.”
