Sonic The Hedgehog 2 is a sequel to the 2020 original – which was a box office hit shortly before the pandemic struck, grossing 320 million US dollars (£231 million) worldwide.
The sequel will see the return of Ben Schwartz as Sonic the Hedgehog, Jim Carrey as the villainous Dr Robotnik and James Marsden as sheriff Tom Wachowski.
The Wire and Luther actor Elba, who recently starred in the superhero film The Suicide Squad, is no stranger to lending his voice to animated properties. He has voiced characters in Zootopia, Finding Dory and The Jungle Book.
Knuckles first appeared in the video game Sonic The Hedgehog 3 in 1994 and quickly became a fan favourite in the franchise and has appeared in numerous games since.
Sonic The Hedgehog 2 is set for release in April 2022.
