This is something Sylvester Stallone posted on Instagram the other day.
It's a pad filled with notes for the sequel to Creed. The actor/director wrote that it consists of 439 handwritten pages that would translate into around about 120 typed pages.
He appears to be working on Creed II, but that's not all.
Look at one of the hashtags on the image (if you can't see it properly, click on the image). Notice the '#drago'?
I guess he's hinting that Dolph Lundgren could be reprising his Rocky IV role as Ivan Drago in this movie. It would work considering Drago is the boxer that killed the Apollo Creed in Rocky IV. The current franchise - Creed - is based on Apollo's son, Adonis, pursuing a career in boxing.
Would be interesting to see if the script has Ivan Drago's son as the main villain.
I'm getting ahead of myself, though. The movie is evidently in the early planning stages and won't be with us for years.
