Unlike the unused post-credits sequence featuring a tease for Deadpool 2, this particular moment is indeed included among X-Men: Apocalypse's deleted and extended sequences on home video. Magneto's recitation of the poem comes after he has killed the police officers with his daughter's locket, and after his screams to the heavens asking if this is the fate that the universe wants for him (which producer Simon Kinberg notes in the commentary was improvised). Bryan Singer says in the commentary that filming the scene was a truly powerful experience that left people on set watching stunned and moved. Said the director,

It was one of the most beautiful things, and I cried at the monitors. [Co-producer Jason Taylor] grabbed a Kleenex; [Simon Kinberg], who very rarely shows emotion, [was] completely emotional. And I remember after the scene happened, Michael finished the scene, I walked across the woods, and I hugged him. And I held him and said, 'Thank you for that gift. Now I need you to do it again [laughs].' Because I have to move the cameras! He said, 'Yeah, sure, no problem!' And he did it again and it was amazing, and it broke my heart.
