The upcoming "Guardians: Soviet Union Superheroes" movie has been the talk of the town with its unique approach to the big budget superhero genre, killer mechanical spider robots and chain gun toting man-bear, but the first full trailer left viewers understandably perplexed. A new trailer effectively rehashes everything from the first, but adds a preamble that provides some much-needed context.

The new trailer includes a voiceover that explains the overall plot of the film and why its four protagonists--Kseniya (Alina Lanina), Arsus (Anton Pampushnyy), Khan (Sanzhar Madiyev) and Ler (Sebastien Sisak)--are capable of superhuman feats; some were born with their powers and others were forcibly altered. The heroes served Russia when it was the Soviet Union, but fell back into the shadows when the regime collapsed.

The second trailer also explains that the wiry half-man, half-machine who might have been leading a militia to attack cities in the first trailer (it wasn't totally clear) is the main antagonist after all, described as an "evil [that] is rising from the shadows of the past."

While the first trailer was visually impactful and a big hit online, it left out much of the aforementioned information, leaving viewers to guess at the significance of each scene. As the trailer's popularity has increased, it's no surprise the film's production company, Enjoy Movies, has issued a much more informative second trailer for English speaking audiences.

"Guardians: Soviet Union Superheroes" debuts internationally February 23, 2017. There is presently no release date for the United States.
