Anakin tries to kill himself

Yes he did and that's why I think this might happen. Lucas likes to link the story together like this. I don't think that this ending would be unsatisfying as after he goes into the pit the Emperor would get him out and he would become Vader. It would still be Anakins choice to turn to the Dark side in the end. And I don't think Lucas would want to show Obi-Wan defeat and almost kill his best friend.

Ok good point. And I must admit that Lucas does like to be repetative, especially with Luke and Anakin, as Luke is meant to be becoming like Anakin in Return of the Jedi. That is why he looks at Vader's robotic hand and then at his own.
But still, I'd like to think that Obi-Wan has no choice but to defend himself and knock Anakin into the bit by mistake.
In fact, I could really imagine Anakin holding onto the edge of a cliff after being knocked down and then Obi-Wan reaching out his hand to help him back up.
But still I would rather him not fall into the pit deliberately. If Obi-Wan knocks him in then that would explain Vader wanting to get his revenge in ANH.

I still don't think that Lucas would want Obi-Wan to almost kill Anakin. Remember that he changed the scene between Han and Greedo in ANH special edition so that Greedo shot first.

Good point KJ, I'm all for Anakin throwing himself into the pit..

I'm not saying that Obi-Wan will knock Anakin down purposely or in an act of betrayal. He just has to defend himself and has no choice.

I agree, that sounds the most like OB1 to me..

OB1 will knock Anakin into the pit. Anakin/Vader will be so deep in the dark side he will have no choice. OB1 will try to turn Anakin back but to no avail, something will be said by Anakin, suring OB1 that there is no hope. Anakin jumping in would leave him no reason for wanting revenge on OB1 in ANH. OB1 will knock Anakin in the lava pit, leave to Alderann pick up Luke and head to Dagobah, Yoda says to take him to Tatooine and keep an eye on "this boy, he is one of the last hopes. Clouded his future is, much like his father, lets hope for the sake of the galaxy this time balance is brought......" fade away, and let the credits role.

Thanx for agreeing with me Dim. And also I don't think Anakin would try to kill himself, because he'll have too many good things going for him, like being one of the rulers of the galaxy alonside the Emperor and being married with children.

But he doesn't know about the children.
And look at it this way. From the age of nine you have been told that you are the "chosen one" and then you become the greatest Jedi ever and a hero in the clone wars. But several very bad things happen to you and you start to turn to the Dark side. You have Yoda and Obi-Wan telling you that your destiny lies with them and Palpatine telling you that you should go with him. How do you possibly choose? You don't so you take the easy way out, only to be saved by Palpatine and then decide that you must join the Dark Side.

Anakin killing himself isn't the main thing that I like about this theory.I like the idea that we never know whether he jumped or if he just fell. It would make the prequels legendary just like the "I am your father" storyline did for the OT.

JM3838- I don't think that Vader wanted revenge on Obi-Wan. Vader managed to kill all of the Jedi except Obi-Wan and Yoda so I think it was just some unfinished buisness. And Obi-Wan was the last real link to Vaders past. He never knew about Luke and Leia so Obi-Wan was the only thing linking him to Anakin Skywalker.

Okay good points there, but I'd still prefer Obi-Wan to beat Anakin. Obi-Wan is my favourite character in the saga and I'd like him to show Anakin just how good he is and that being the chosen one doesn't mean he can beat anyone he likes.
As I said before, in ANH you can tell Darth Vader is against Obi-Wan because of revenge. It wouldn't make as much sense if Obi-Wan hadn't had knocked him in and instead he had tried to commit suicide.

Thanks for backing me up a little bit, Darth Daft. Obi-Wan is also my favorite character(Han Solo a close 2nd). Anakin jumping or falling just doesn't make sense. OB1/Ben should knock him in, remeber "When we last met i was but the apprentice, now I am the master." When they last fault OB1 defeated him, because he was the master. This tells me that Anakin doesn't jump or fall

Yes, I completely agree with you JM3838. If Anakin was willing to kill himself to escape from the Dark Side (just like Luke was in Cloud City) then you'd think he'd have the guts to just not join it at all.
I'm sticking with the theorie that Obi-Wan knocks him in.

The idea isn't that he jumps to avoid turning to the dark side, he jumps because he has already turned and he knows that is where his destiny lies.
If this scene takes place at the end of Ep3 then Anakin will have already turned and killed all of the Jedi except two. Obi-Wan and Yoda. He is already Darth Vader. Then Obi-Wan and Yoda show up to try and turn him back and he feels ashamed and helpless because he knows what he has become. He doesn't think there is any way back and is scared so he jumps. He doesn't want to accept that he has become Darth Vader and only does when he is saved by Palpatine and becomes more machine than man.
Luke will of course succeed where Obi-Wan and Yoda failed and turn him back in ROTJ.

Ok, that's a good theorie and certainly very possible. BUT STILL, I have to stick with my usual theorie that Obi-Wan knocks him in while Anakin is on the Dark Side and is Darth Vader. He is saved by Palpatine and has become even more angered because of what Obi-Wan has done. Nice and simple.
I must admit though, I guess your theorie would explain more about why Darth Vader still has that little bit of good left in him.

Well we will just have to wait and see, but the more I think about this the more I like it.

I thought it sucked but now I'm beggining to change my mine.

Me? Heh heh, I'm still sticking.

When I first saw this I didn't like it either but now I do. Another twist would be if Obi-Wan and Yoda don't try and save him once he has fallen. They just leave convinced and maybe a bit releived that he is dead.

Yeah...that might peeve him off just a little. But it's more SW to try to save him..
