Daft Gemini Man-inspired questions

I recently described the synopsis of Gemini Man as ‘Will Smith vs the Fresh Prince’. Then I realised I’d like that to be literally true—imagine a young, loudmouth Will in 90s Jordan gear, who is somehow an assassin, hunting down an older version of, say, Agent J from Men in Black.

So, my question is: which characters played by the same actor would you like to see fight/hunt/interact with?

Take Liam Neeson for example. Bryan Mills from Taken vs Qui-Gon Jinn doesn’t seem like a fair fight. But could Mills take Darkman? And why stop at just two characters?

Or, in a similar vein, which actor’s roles could conceivably be the same person at different ages? Josh Brolin: what happened the big brother from The Goonies to turn him into the dodgy CIA guy from Sicario? And how did that man become Thanos?

Yes, it has been a slow day. How did you know?
