Henry Cavill, known for his role as Superman, has made a cameo as a Wolverine variant, dubbed 'Cavillrine,' in the Marvel film 'Deadpool & Wolverine.' The role came about quickly after the DC Universe's decision to reboot with new actors, leading Ryan Reynolds to reach out personally to Cavill. Cavill's commitment to the role included enduring physical discomfort from smoking cigars during filming. Both Reynolds and director Shawn Levy have expressed their admiration for Cavill, highlighting the playful and affectionate nature of his involvement. Cavill also humorously referenced his infamous CGI-ed mustache from 'Justice League' in an Instagram post. The cameo has generated significant excitement among fans and has been seen as a nod to the rivalry between Marvel and DC.
