My ultimate guest would be Jackie Chan.
I would like to see Doug Jones as I was gutted he could not make this years event.
Michelle Yeoh and Sonequa Martin-Green.
Craig Charles as he is the only main cast member of Red Dwarf I have not yet met.
Burt Ward would be nice.
Ezra Miller, Ray Fisher and Gal Gadot from Justice League.
Wentworth Miller would make me happy.
Felicity Jones, Diego Luna, Riz Ahmed and Ben Mendelsohn from Rogue One.
The Dudley Boys, Lita, Jake Roberts, Scott Hall, Ric Flair (if he was well enough) Shawn Michaels and Steve Austin.
Any of these wonderful people would be great.
