Fan CastingGreen Lantern:

The movie starts where number 2 left off, we see Hal fighting the Last Guardian in a time stream tunnel the force of the time tunnel destroys the Last Guardian and is about to do the same to Hal but then this yellow energy grabs him and takes him out of the tunnel, we see him floating in space and his eyes turn yellow as he smiles. Back in present day all the lanterns are in a massive space battle fighting each other until John & Arisia are able to settle everyone, however Parallax then arrives and decimates half of the armies. All the Lanterns decide they must team up together to stop Parallax. The Lanterns make a line of defence but Parallax clears through it knocking them all unconscious except for John & Carol, they make a backup plan and head for Earth. John Calls for backup, they arrive at Coast City and are met by Green Arrow & Flash. Parallax almost kills Flash & The lanterns but then Green Arrow shoots him through the chest giving Hal a few moments to think clear and then Carol gets through to him. Hal realises the pain & death he’s caused so he flies into the atmosphere and releases a burst of energy and the lanterns send parallax into the sun. Hal is now a normal human and him and Carol go to live a normal life. Mid Credit Scene:- We go to William Hands grave and we see his hand burst through the ground with a black ring. End Credit Scene:- Hal is looking at the sunset with Carol and he glows green and we see him turn into the spectre.
