Does anyone else watch Collider Heroes on YouTube ?? If you don't you should.
Anyway John Schnepp mentioned in one of the last episodes that there could be a 30min extended cut of Infinity War coming. Predominantly adding already filmed footage giving more of Thanos' backstory. This apparently came from the original comic creator of Thanos himself. So perhaps some inside info.
Sure it may not happen, but I sure as hell hope it does ! How awesome would that be giving even more reason/explanation as to why Thanos does what he does.
Once Avengers 4/IW2 is out next year, I really hope they release a 10 year 4K UHD box set with all the Marvel films. Either that or I'll be getting the Disney streaming service.
Here's an article on it if anyones interested.
