Stephen Amell has been tapped to play Casey Jones in “Teenage Mutant Ninja Turtles 2” for Paramount and Platinum Dunes.

Megan Fox is set to return as April O’Neil. Will Arnett is also returning. David Green is directing the pic. Plot details and information on other returning cast members are still unknown.

A loner who becomes an ally of the turtles and a love interest for O’Neil, Jones is a fan favorite of the series going back to when Elias Koteas played him in the 1990 New Line pic.

Michael Bay is producing along with his Platinum Dunes partners Brad Fuller and Andrew Form. Josh Appelbaum and André Nemec are penning the script.

Amell tested with a half-dozen actors over the weekend, but it was his chemistry with Fox that led to the studio eventually giving the role to the star of CW’s “Arrow.” Paramount had no comment on the casting.

The “Turtles” franchise is one of Paramount’s top properties following its success last summer, when it earned $191 million domestically — so much so that Paramount dated the sequel for 2016 before even locking down a director or cast.
