本片是我個人09年的第一名，同時也覺得是庫隆尼生平最好的一部代表作，不過讚美之辭已經太多，不需要在此重複，反而我想點出，以40歲以下居多的PCDVD網友，大概沒有注意到本片眾多主題曲中最重要的一首，也就是庫隆尼最後再度搭機飛上雲端時的be yourself（非同名的up in the air），原作者和主唱仍然是1960~70年代的英國民謠歌手Graham Nash，Nash今年已經高齡68了，比Eagles還老，然而這麼好的一部電影，最重要的主題曲，還是得找這種老傢伙才能寫出該有的韻味，再過10年怎麼辦？

Be Yourself by Graham Nash

How does it feel
When life doesn't seem real
And you're floating about on your own
Your life seems uncertain
So you draw the curtain
Pretending there's nobody home
Don't theorize
Look in your eyes
They can't tell lies
Though you may disguise what you see
The mirror is free
We once had a savior
But by our behavior
The one that was worth it is gone
Song birds are talking
And runners are walking
A prodigal son's coming home
Don't theorize
Look in his eyes
They won't tell lies
But if he defies what you see
He'll give you a key
Be yourself
Be yourself
Be yourself
Be yourself
We needed a tutor
So built a computer
And programmed ourselves not to see
The truth and the lying
The dead and the dying
A silent majority
Don't theorize
Look in their eyes
Are they telling lies
The ones that they learn on T.V.
What a way to be free
Be yourself
Be yourself
Then you can free yourself
Free yourself
See yourself
Then you can see yourself
Come on and see yourself
See yourself
