Batman Beyond fan casting

We’ve all heard of and yearned for the idea of a Batman Beyond movie with Michael Keaton playing old Bruce Wayne. But along with that who do you think could play the future Dark Knight? And while we’re at it who do you think should play Terry McGinnis if he ever makes an appearance on Legends of Tomorrow (because he totally should be on that show)?

Will Friedle would be perfect for Terry, should he appear on Legends. He’s got the physique and sometimes has the hair for it. It’d be cool to see a voice over actor play the live action version of a character they voiced.

Don’t know about movie casting. I adore Keaton but I don’t see him as the hard edged older Bruce as much as say…Affleck. If it’s in the DCEU, that’s the logical choice anyway as long as he sticks with Batman.
