Mr Cavill is famed for his role as DC Comics’ superhero Superman while Mr Johnson, who famously portrayed WWE wrestler The Rock and starred in the Fast and Furious franchise, is due to play super villain Black Adam, also a DC Comics character, in an upcoming film.
But writing on social media Cavill, who is an ambassador for the Durrell Wildlife Trust, fuelled speculation they may be seen on screen together in the future.
Together with a picture of the two men sharing a drink, Mr Cavill wrote: ‘Merry Christmas and a happy New Year from Superman and Black Adam Dwayne The Rock Johnson. Today we drink like gentleman and come together as friends. We’re excited for what the future brings. #DangerousGentleman #DCWorldsWillCollide #Superman.’
