I believe he wrote the Lethal Weapon 5 script on spec, so there's not much to see there.
The two recent directing deals are promising, and the first movement his career has had in five years, but as you've both said, they've yet to come to fruition.
Hopefully I'm just babbling on about nothing, because Black is a terrific writer and director, and it would be a shame if his lack of recent success kept him from the Iron Man
job. As far as comic book properties go, it's perfect for him.
