Like in Smallville and Lois & Clark. Can see Rachel Brosnahan doing it.
Or the Marvel banter improv?
Aside from Superman Returns and Man Of Steel most versions of Clark and Lois banter.
We know Gunn can do that, be akin to Starlord, Rocket Raccoon and Gamora.
We haven't had it on film since Christopher Reeve, only on TV with L&C, Smallville and S&L we got it. With Gunn writing & directing and with David Corenswet and Rachel Brosnahan it's possible.
