The Beat has some info and basically an OK from Mantlo's brother Mike to go ahead and see the Guardians of the Galaxy movie.

I want to use this as an opportunity to say that while i often knock his writing style, i hope it's obvious that i think Bill Mantlo's contributions to the Marvel universe were HUGE. In addition to Rocket Raccoon, here are some other character creations (certainly not comprehensive):

Cloak & Dagger
White Tiger
U-Foes
Ursa Major
Jean DeWolff
Sabra
Arabian Knight
Woodgod
Razorback
Swarm
Captain Universe
Firebird
Bug (and all the secondary Micronauts)
Hybrid (and all the secondary ROM characters)

Of course we shouldn't neglect the artists' contributions or the way later writers built off this stuff. The recurring theme of my timeline project is that the sum is greater than the parts. But Mantlo contributed so many of the parts (and in terms of events and storylines, much more than is reflected by the above list).

I'm glad to see Marvel doing something in the right direction for Mantlo. The question of character creations is in my mind a difficult one due to the "sum of the parts" issue (the characters in the Guardians of the Galaxy movie illustrate that very clearly), and Mantlo's specific issues are part of a larger societal problem (and one that Obamacare didn't really fix, per this moving article). Min and i do a monthly recurring donation to the Hero Initiative, but Mantlo's situation is unfortunately not going to be fixed with money. So it's good to see the Guardians of the Galaxy getting him some recognition, too.
