Question: I have heard something about Cube having an alternate or extended ending. Are there any videos of this by chance?
Answer: From Lost Media Wiki: According to several eyewitnesses, in certain theatrical screenings of the film, the scene in question was shown. It allegedly depicts Kazan walking out onto a beach (or a cliff's edge, depending on who you ask) on a purple alien planet, overlooking an endless ocean, as mechanical grinding noises are heard. As he turns around, both his footprints and the cube's exit itself vanish. Some have also reported that the sky is then shown, full of exoplanets. A pinch of salt is needed; however, this statement does have 4 sources.
Question: Is it revealed, in the Cube trilogy, the destiny to which Kazan is reserved when he walks into the bright light?
Answer: No, but given the nature of the organization behind the Cubes, it can be assumed he was either tracked down and executed or detained in order to place him back into that Cube or into another version.
Well due to his amazing luck and how most of the other people around treated him he may have been put back in The cube and this is not the first time he has escaped eventually they will get tired of him and leave he back on the streets alone covered in blood of his former friends.
Answer: In an alternate ending of the cube we discover that the cube was built on another planet so Kazan died.
Answer: If you watched Cube Zero, we see the same blinding white light when Owen makes it to the exit, but when he walks through it turns dark and he is chained up. He is then asked whether or not he believes in God. When he says "No," he is incinerated. Apparently, no one has ever said "Yes," so we don't know what happens if someone were to say "Yes." It is very likely that Kazan ended up in the same situation.
Answer: Not to my knowledge. The director said on Twitter/X that there was an extra scene during the ending that had been shot but that it was immediately removed from the film after the first assembly cut. He also said it will never be seen and joked that he "burned it and stomped on it." (Chances are the footage is just lost.) So I'd assume whatever it is REALLY didn't work or was too silly.
