I always imagined the best way to go for the Green Lantern teaser poster campaign would be to have four large posters appear in theatres and the internet completely unnanounced, just suprise everybody... A little bit like that very first Ledger joker photo over a year ago.
The first poster is an image of a small group of what look like robed dwarves (the guardians) standing with their backs to us, in front of Oa's power battery, basked in green light. It just says "In Brightest Day, In Blackest night..."
The second poster is of a massive beastly looking humanoid mostly bathed in darkness(Kilowog), the only tantalising glimpses of him are illuminated by the glowing green ring on his huge finger (reminiscent of Ang lees Hulk poster). It just says "No Evil Shall Escape My Sight..."
The third poster is of a wiry, sinewy looking man, hdden mostly in darkness (Sinestro), again the only details (including the moustache) are lit by the rings green light. It just says "Let Those Who Worship Evils Might..."
And Finally, the fourth poster is Hal Jordan Standing there fully illuminated, the poster is completely lit up by the glowing ring on his finger that he is pointing straight forward at us... It says underneath "Beware My Power, Green Lantern's Light!"
I really do think SPECIAL care has to go into the green lantern flick, He's the ONLY major league A-List Superhero who's never received live-action treatment (I dont count the JLA pilot, and if your in any way intelligent neither do you)... Odd considering that his movie franchise has the potential to be the absolut best of them all! It has everything! This could be the Lord Of The Rings of superhero trilogies... Think About It!
