While Avengers: Infinity War had no problem showing the brutal lengths Thanos is willing to go to obtain all six Infinity Stones, there was one assault by the Mad Titan that notably took place off-camera: the attack on Xandar to gain the Power Stone.
During a surprise Q&A at an Iowa high school, Infinity War co-director and University of Iowa alum Joe Russo explained why Xandar's reckoning took place off-camera before the events of the Marvel Studios sequel: to save time in the film, which already clocks in at just under three hours, and to avoid repetition with the rest of the wholesale destruction on-screen.
First seen as the central plot device in director James Gunn's Guardians of the Galaxy, the Power Stone was kept on the Nova Corps' home world at the end of the 2014 film.
That well-intended defense was ultimately ineffective as, at the beginning of Infinity War, Thanos has already secured the Infinity Stone. Thor informed the Guardians shortly after his rescue that Xandar had been decimated a week earlier.
Directed by Joe and Anthony Russo, Avengers: Infinity War stars Robert Downey Jr., Chris Evans, Chris Hemsworth, Mark Ruffalo, Jeremy Renner, Scarlett Johansson, Anthony Mackie, Paul Rudd, Elizabeth Olsen, Tom Holland, Benedict Cumberbatch, Chadwick Boseman, Chris Pratt, Zoe Saldana, Dave Bautista, Bradley Cooper, Vin Diesel, Tom Hiddleston, and Josh Brolin. The film is playing in theaters in everywhere.
