The final battle scene in Avengers: Infinity War was pretty epic. If you haven't seen the movie, I wouldn't recommend reading any further. 

At the end of the film, we witness some jaw-dropping events. For the first time in Marvel history, they kill off several of their most lucrative characters. Deaths were teased prior to the movie's release, but no one was expecting such a massive scale of destruction. While we won't go into details of who died here, those who watched the film know that last battle was emotionally jarring. 

Many fans weren't fooled though. Several characters who died are contracted for multiple movies with Marvel Studios, some of which are currently in pre-production. We all know somehow, many of those characters will be making a return, we just don't know how yet. Don Cheadle, who plays War Machine in the film, recently appeared on The Late Late Show with James Corden along with several other cast members/superheroes from Infinity War. Don drops a freestyle to some old-school beat-boxing, and hints that the final scene isn't the ending for everyone. 

"We Avengers/Now you remember/We did this thing/We're gonna be back in December," he raps, referencing the fact that reshoots will be bringing back cast members to complete Avengers 4. "That's the word I heard, lots of reshoots/ you know that final battle scene was just the "poo-poo."

Thanks for the reassurance, Don!
