At least according to examiner.com http://www.examiner.com/article/avengers-3-movie-seems-to-follow-the-thanos-quest-comic-book-storyline -where you can watch the Thanos clip- who are simply repeating the information everyone else in comicdom is.
Now what did I tell everyone a good ways back when they were being ripped off -price-wise- on anything Sub-Mariner related ("It's the big mystery movie coming up!! Buy the goods now!")? I wrote, it's there for all to see, that there was no Sub-Mariner movie.
But as Marvel movie news far exceeds news and excitement from DC movies....my treat!
According to ComicBook.com on Thursday, there is the speculative notion that Marvel Studios' "Avengers: Infinity Wars" two-part comic book movie and the line-up of other films in the Marvel Cinematic Universe could follow along a similar path as "The Thanos Quest" which was written by Jim Starlin and drawn by Ron Lim. The plot of that story entails Thanos' resurrection by Mistress Death to assist her in accomplishing the mission of exterminating half the universe's population.
Perhaps this was Death's efficient method of culling the herd, but Thanos' intended to repay death in seeking out the six "Soul" or "Infinity Gems" and them joining them together with the Infinity Gauntlet. "The Thanos Quest" is a two-part series that leads into the three consecutive comic book limited-series of "The Infinity Gauntlet", "Infinity War", and "Infinity Crusade."
Take notice the "Infinity War" comic book title is the same as the Marvel Cinematic Universe's sub-title to "Avengers" third and forth movies. One may speculate that those four comic book titles are being condensed into the two-part Marvel Studios version. The Infinity Gems are known as the Infinity Stones in the theatrical variant.
Right now, Thanos' objective is to collect what would allow him to harness the Mind, Time, Reality, Soul, Space, and Power. This was his objective in "The Thanos Quest" as he embarqed on his journey to acquire them from the cosmic entities that are in current possession of them. The Marvel Cinematic Universe, the locations and the occurrences of the Infinity Stones are as follows:
The Space Gem
Is also the Tesseract, the cube shaped artifact first seen in "Captain America: The First Avenger" that was initially acquired by the Red Skull back in World War II. It eventually allowed the Chitauri to invade Earth during The Battle of New York at the hands of Thor's villainous brother, Loki. This gem currently remains in Asgard.
The Reality Gem
Also, known as the Aether in "Thor: The Dark World", this was in a constantly seen as red in color and has made its way through space and time. It can change regular matter into dark matter and had been coveted by the Dark Elves who were born again into the universe from the darkness that King Odin had spoken of. It now is in possession of The Collector, played by Benicio Del Toro, on Planet Knowhere.
The Power Gem
This was the sought after artifact by Peter Jason Quill, a.k.a. Star-Lord in James Gunn's "Guardians of the Galaxy." He had attempted to take it to The Collector on Planet Knowhere and this is where the audience learned of all six "singularities" where he spoke of how even the most powerful of beings who had tried to harness its power, but failed. Ronan the Accuser took possession of it and then later Rocket distracted Ronan while Star-Lord made a break for it to grab the Power Gem. The gem is currently located at the Nova headquarters on Xandar.
The Mind Gem
This is found to be in Loki's scepter. It was given to him to control the minds of those who could manipulate the Tesseract into bringing for the Chitauri during the Battle of New York. With a touch of his sceptor to his victim, he could easily control their free will. This was last scene during the end-tease of "Captain America: The Winter Soldier at Baron Von Strucker's underground Hydra facility along with captives Scarlet Witch and Quicksilver.
This leaves the continuing saga of the Mad Titan Thanos to find and acquire the gems. With the aforementioned mentioned brings for moving forward with Marvel's phase three.
"Captain America: Civil War"
In this film which is thought to lead to Tony Stark and Steve Rogers opposing each other, an Infinity Stone will likely not enter this film. Loki's scepter may come into play and could connect with the "over-arching" "Thanos Quest" storyline. There's a thought that if this scepter is acquired by the Avengers, one could contend that it would stand to reason it would be in this film. This film is scheduled to be released come May 6, 2016.
This is where it may get interesting. In the comic book storyline, the Sorcerer Supreme plays a key role in Thanos' quest for the Infinity Stones. In this film, where Benedict Cumberbatch is rumored to play the starring role, a new stone could be brought into the mix. There may even be a post-credit end scene with Thanos, who is known to be played by "Goonies'" Josh Brolin, to make an appearance in the tease. This film is slated for Nov. 6, 2016.
"Guardians of the Galaxy 2"
Director Gunn has mentioned he's already working on the story/script and it looks like this film would only make sense for Thanos to appear. Likely to send someone to do his bidding to find the Aether or the Reality Gem after the destruction of The Collector's museum. This comic book movie is scheduled for May 5, 2017.
This is where there could be a significant impact in the Marvel Cinematic Universe. There are a few things to keep in mind here as Ragnarok, also known as Surtur who is a malevolent fire demon, could have wiped out Asgard as told in the comics. It could only be after the destruction of Asgard is where Thanos collects the Infinity Gauntlet as seen in the armory of Asgard in the previous "Thor" movie. This film is scheduled to be released come July 28, 2017.
There isn't a frame of thought here where there would be any kind of tie-in to Thanos' quest for the stones. One may wonder there could be just an end tease to this movie entailing Thanos seeking out the final stone. This comic book movie is scheduled for release come Nov. 3, 2017.
"Avengers: Infinity War Part 1"
One could only ascertain at this point, in the first portion of the comic book movie that Thanos acquires all the Infinity Stones. Of course, likely the last and final gem and is has finally put it all together into the Infinity Gauntlet. This was likely seen in the trailer at the Marvel press event last Tuesday showing Thanos wielding the gauntlet with gems blazoned. The start of the two-part "Avengers 3" movie is scheduled for May 4, 2018.
