My wife Karen Gillan reteams with Jumanji co-star Awkwafina for Shelly:

My wife Karen will play Dianna Park, the former high school tormentor to the said Shelly (Awkwafina).
For my wife Karen she gets to have the shoe on other foot because when she played Eliza Dooley in Selfie she recounted her own high school tormentor Corryn McWaters (my wife Julianna Guill).
Funnily enough Shelly is the name of the Jumanji avatar played by Jack Black.
