I've said many times that
high-tech Batman aren't my cup of tea, and with the exception of the TDKR tank and the Tumbler, I've never been a fan of modern Batmobiles and prefer them to remain
"relatively classic" cars
(like Anton Furst's, Batman Tas, Battinson's muscle cars, etc).
That being said, since Gunn talked about the possible influence of
Batman & Robin comics from Morisson on
The Brave and The Bold movie, I'd really like to see the film share that same vibe that Frank Quitely gave to the title, and thus, see his flying Batmobile.
I know a lot of people are craving a more classic Batman world on film, but since they are going for this
non-academic duet with Damian for Robin's return to the big screen, I guess stealing Dick's Batmobile to give it to Bruce wouldn't be a problem.
This kind of vehicle would certainly be different from Reeves' but also completely new to the audience. I can picture it being quite popular. As said above, I really think the
"dark but colorful" approach found in Morisson & Quitely's issues would be an excellent direction to revitalize Batman on screen, at least visually, and tone down the inevitable feeling of saturation.
