Looks like this is a go. Like Willow, Rocketeer was an ambitious flop, but Disney+ is giving it a second chance.

I think it'd be actually cool for most of the original cast to return as supporting characters or cameos, if possible. Would be interesting to see Terry O Quinn as the later years of Howard Hughes (Who invented the jetpack in the original movie)
