In the book 2001: A Space Odyssey it was made explicitly clear that the monoliths were the emissary(s) of a benevolent alien species whose main aim was the advancement of less evolved species;
Night after night, the spectacle of those four plump man-apes was
repeated, until it had become a source of fascinated exasperation,
serving to increase Moon-...
In the film 2001: A Space Odyssey, the nature of the black monoliths is deliberately left unclear.
The director, Stanley Kubrick, stated in a 1968 interview with Playboy that:
You're free to speculate as you wish about the philosophical and allegorical meaning of the film—and such speculation is one indication that it has succeeded in gripping the ...
Per the film's Directors/Screenwriters Commentary, Thanos' motivation for deciding to gather the stones is that he finally (after many years of searching) learned the location of the lost Soul Stone. Before this he seems content to get on with obliterating one planet at a time and making sure that he knows roughly where the other stones are, safe in the ...
There is no right answer that we know of. Below I present some evidence both for and against the ending being halo-induced; both arguments have pretty good evidence in support of them. Although there has recently been a new series set 10 years after the movie, we still don't know whether or not it is halo-induced (see Edit 2). After doing ...
Clues about Rhaegar and Lyanna, together, or by themselves:
Rhaegar is (presumably) mentioned in Daenerys' perspective, in the House of the Undying prophecies (also here) like this:
Rubies flew like drops of blood from the chest of a dying prince, and he sank to his knees in the water and with his last breath murmured a woman's name.
Presumably this ...
Here's another answer - and it is based on a passage in the book by Arthur C. Clarke:
The monoliths look like tombstones. (As, in the book only, Dr. Heywood Floyd thinks, when he first sees a monolith.)
Therefore they represent Death - and Transfiguration, too. (Clearly referenced by the Strauss music used in the movie!:)
Philosophically speaking, their ...
'Avengers: Infinity War' Doesn't Actually Have a Mind Stone "Plot Hole"
Thanos has been culling populations for decades; He kidnapped Gamora around 18 years ago but has had his genocidal tendencies for far longer. He’s quietly sought Infinity Stones for years. He sent Gamora hunting for the Soul Stone long before the first Guardians of ...
Pretty sure she was conceived without much forethought.
All the executions by fire aroused the king and, while he and his wife had slept in separate chambers for some years and avoided each other by day as well, Aerys would always claim his marriage rights after such an execution by fire, brutally abusing his wife in bed.
A Feast for Crows, Chapter 16
I never felt that from watching the movie, and one thing that can confirm that is the new Minority Report series: that show continues the movie's story and now we can know for sure that everything that the movie depicted was true from start to finish.
No, Qrow did not cut Winter, because no one cut Winter to begin with.
Someone needs to get better at Photoshopping, because in this picture from Volume 3, chapter 3 there clearly is no cut on Winter's shoulder.
In answer to your specific questions:
Are there known dream scenes where he has no wedding ring?
No. In every dream sequence (with a single exception where his hands are in his pockets throughout the short scene) Cobb is always depicted as wearing his wedding ring, including those set in flashbacks prior to Mal's death.
Are there known real world scenes ...
This was also dicussed on another forum whereby the consensus was also: maybe, maybe not.
Some of the main points someone mentioned in support of the dream-ending were (the following are quoted):
The aforementioned comment from the clerk about the prisoners "dreaming whole lives for themselves".
They use Anderton's old eyeballs to get into the Pre-...
The is how the events unfolded:
Rhaegar weds Princess Elia Martell some time before 280 AC.
Princess Elia gives birth to two of his Children; Princess Rhaenys (born 280 AC) and Prince Aegon (born 281-282 AC). Maesters inform the Prince that Elia won't be able to bear any more children due to her poor health.
Rhaegar tells Elia that the Dragon must have ...
