All the DC movies are going to feature crossovers of the classic Justice League of America characters, so even though the Green Lantern movie was not popular, there's a great chance Hal Jordan is not done with the silver screen just yet.
This book is also red hot because Neal Adams is the artist of the moment, and this is THE Adams issue and title. The original cover art for Green Lantern #76 just set a record for Adams art, selling for over $400,000.
