You may know me - Who am I?

Though I am just a man,
You may be quite a fan.
You may think I cannot die,
You may have seen my taxi fly.

Later I saved everyone,
I'll make you cry, even the sun.
Then suddenly I was dead,
Don't let that get to your head.

I took some time, went back and forth,
Found great strength, and great worth.
Thought I could settle down,
That didn't work, just made me frown.

I have many well known friends,
They think we can be thrown away, in the end.
Figure now who I may be,
And where you often see me.

• At first I thought "could it be bubble buddy?", and now I can't think about the real answer without that in my head. – Quark May 29 '15 at 21:12

Thank you for all the remarks that suggested improvements/corrections. Much obliged. Also. Nicely crafted puzzle.

• Can you better explain how it fits each line / stanza? – Engineer Toast May 29 '15 at 21:18
• Welcome to S.E. Puzzling. Can you please add some justification as to why you believe that fits the answer? I might also recommend looking at some other puzzles to see the format often used when answering riddles. Especially, I would like to point out the '>!' formatting option at the beginning of a line which will hide your answers. – Aggie Kidd May 29 '15 at 21:18
• Welcome to puzzling SE! You might want to give a more detailed explanation (It'll avoid you getting downvotes) It's certainly an interesting answer, I see Die Hard fitting for the first paragraph but you kind of lose me after that! – Spacemonkey May 29 '15 at 21:19
• Another movie where he seems to have retired and is unhappy is G.I.Joe: Retaliation. Good explanation, you seem to have found all the movies first : ) – Spacemonkey May 29 '15 at 21:26
• Fifth Element, not Fifth Sense ;) – LeppyR64 May 29 '15 at 22:11

Are you...

Bruce Willis?

Bruce Willis is a man, and as an actor he has lots of fans. He cannot die in Unbreakable and flew a taxi in The Fifth Element

Later I saved everyone, I'll make you cry, even the sun. Then suddenly I was dead, Don't let that get to your head.

He saved everyone in the Die Hard films and in Tears of the Sun, which is what the 2nd line is referencing (Thanks @Spacemonkey). He turned out to be SPOILERS!! dead in The Sixth Sense.

Bruce Willis went back and forth between different types of movies? Or maybe making/not making movies? And ended up not being happy if he wasn't filming? (I'm not 100% sure about this one)

He appears with many other well known action heros in The Expendables, but alas, he is not expendable. You're Bruce Willis! And I often see you in these films.

• Tears of the Sun (war movie) for the 2nd paragraph - and I have a feeling the saving anyone clue is probably more for Armageddon as in the scope of that movie he truly saves everyone For the third going back and forth taking his time, it might be a reference to the timetravel movie Looper – Spacemonkey May 29 '15 at 21:20
• Nicely done. Unfortunately just after the first. +1 for sure though. – Aggie Kidd May 29 '15 at 22:21
