So...apparently, Deadpool is surprising everyone this year, by not only releasing DP2 earlier this year, but apparently, they had also filmed Deadpool 3 during the filming of 2 and kept it pretty under wraps until now. Not sure how "real" this is, but if it is, in fact, true, this will be one of the biggest "surprise" for a franchise to pull off, ever! In fact, it might have some serious validity to it, because two major movies have now been pushed back because of its surprise announcement, including X-Men: Dark Phoenix. And they don't just do that unless there is some seriousness behind all this, so I guess we'll have to wait and see.
