Considering how much of an immediate OBSESSION Avengers: Infinity War inspired in its audience (to the tune of a couple of billion dollars, in fact) it's incredible that there are any revelations to be had about the Russos' stunning ensemble. Usually, we'd all have hoovered up all of the production secrets and hints of deleted scenes and alternate versions by now as part of the pre-release process.
But because Marvel were so tight on spoilers, there wasn't as much of an opportunity for that and it's taken until the Digital release of the film in the US for any of these new revelations, qualifications and theory killing info dumps to make it to fans. And trust me, there's a lot on that home release that will change how you see Infinity War.
It's not out on Blu-Ray for a while yet and other territories have to wait to get it on digital, but for now there are some great bits of information about the film that you can now know...
Infinity War obviously starts with a bang as we see Thanos and the Black Order's impact on Thor's refugee ship and watch as both Heimdall and Loki are killed off in quick succession. The former might have been expected, but the latter was much more of a shock and the commentary has Joe Russo explaining why they did it:
"Part of what we wanted to do, out of the gate, was to unsettle you as you're watching the film. You're sitting in the theater thinking, 'Most characters in the Marvel Universe have been safe for a decade.' And we wanted to knock you off-kilter and make the audience understand that the stakes were going to be significant and the cost was going to be very high in the movie."
Essentially, Loki was the Trojan Horse holding the film-making team's intent to make Infinity War considerably different right away. This was them foreshadowing the lack of a happy ending as well as confirming Thanos' power, which is why they allow him to break the Tesseract so easily.
Stephen McFeely and Joe Russo also confirms in the commentary that Thanos is dealing with some unfinished business with Loki when he kills him:
SM: "Remember, he [Thanos] had a relationship with Loki, even if it was off-screen where he entrusted him with a duty in 'Avengers 1' and Loki failed.JR: "He's [Thanos] making him [Loki] pay."SM: "Thanos has a long memory."
