Blumhouse's freaky ending explains how the Physique Swap Magic works
Could Vince Vaughn return for a sequel?
As it stands in the end, Vince Vaughn is unlikely to return if a sequel for Freaky comes out. The Blissfield Butcher died twice, the last time he was used … it would be superfluous for a third serving. Unless Vaughn's butcher had a twin brother? However, I wouldn't rule out that Christopher Landon did something crazy with Happy Death Day 2U by making Tree part of a time warp and parallel universe so that more of the magic can continue from the original. The magic of the knife could be even more than we've seen before. And a sequel to Freaky just wouldn't be the same without him.
