The Rock in a reboot of Waterworld

when all is said and done this was a solid if overlong movie but the history behind it makes it so Hollywood wouldn't be too eager to give this movie another go. but if the rights still belong to a studio (?) or could be obtained at a reasonable price, I think there's at least a reboot and maybe a sequel to that in it

The Rock would be a big draw and it's the type of movie and part he could pull off. they could insert a little bit of humour to the proceedings (I don't recall any of that in the original movie) and maybe make it more palatable that way

as a serious action movie / dystopia flick it would also still work but in that case I don't think The Rock is the best fit. in fact you might be better off with Vin Diesel who has done SF in the past, but I don't think he still draws the crowd he used to apart from F&F movies
