We're still in the early days of Deadpool 2 announcements. Ryan Reynolds is confirmed to be returning as Deadpool/Wade Wilson – the first movie was very much his baby, and it's inconceivable that Fox would move ahead without him.
Morena Baccarin has teased her possible return as Wade's partner Vanessa Carlysle, and TJ Miller has said that he 'believes' that he'll be back as sidekick Weasel, but wasn't ready to give us official confirmation.
Negasonic Teenage Warhead (Brianna Hildebrand), Colossus (Stefan Kapicic) and taxi driver Dopinder (Karan Soni) are all in line to return, as is Deadpool's flatmate Blind Al (Leslie Uggams). Hildebrand teased that her character has "grown and matured" but still has the "essence of a punk kid".
