朋友說當年睇完《迷幻列車》（Trainspotting），立即衝去買了條緊身牛仔褲及電影原聲大碟。他妄想自己可以成為Ewan McGregor，在自己的房間邊抽煙邊聽soundtrack，就可以逃離現實。事實是他太肥穿不下，香港也不是愛丁堡，他又不是邊緣青年。結果第二天他仍然要上學，面對現實世界的殘酷（當然比起現在的學生可能叫幸福了）。
21年後《迷幻列車2》（T2 Trainspotting）上映，朋友反而瘦下來，穿得上緊身牛仔褲了。「這次沒有了以前那股衝勁。」他看完說的第一反應。大哥，角色跟導演都人到中年了，又癲又狂的Begbie（中文譯名巴閉，妙）要吃偉哥才能「扯旗」，你還期望他們一味死衝衝衝嗎？換來的是中年人面對困局的應對。
上集結局Renton私吞了大家販賣毒品的錢，笑笑口離去，本應是人生蠃家，今集卻因為在荷蘭與老婆離婚，只好死死氣回到有兩大仇口：Begbie同Sick Boy（上集醒了Spud四千英鎊，應該無仇）的老家愛丁堡。如果這4個角色以前是廢青，現在就是廢中了，在世人眼中絕對一事無成，但性格仍然不變：Begbie逃獄後繼續做狂人打家劫舍；Sick Boy繼續想搵大錢，決意改裝老人酒吧做桑拿；Spud繼續做毒蟲；Renton繼續聰明，識扮開BnB呃政府錢。
人到中年，世界轉變，唯獨自己不變，都是無錢、無前途、無希望、無家庭，唯獨是蘇格蘭的廁所好像不再那麼骯髒（笑）。連身體都唔自己聽話，choose life？其實好似根本無得選擇，性格使然，無論怎選擇大家永遠都離不開所謂的命運，「choose watching history repeat itself」。人喜歡上癮與依賴，以前愛毒品，現在轉成是手機、電視劇、跑步，其實那本質仍然不變。就像是機會來了，永遠總有人會選擇出賣別人。20年後，Danny Boyle又可以再拍一套廢老版《T3》，大家可能是對某人的遺產虎視眈眈。
（順帶一提，兩集《迷》的編劇John Hodge，第一套寫的電影作品叫《同屋3分驚》（Shallow Grave），一樣是Danny Boyle執導及Ewan McGregor主演。講3個同屋主因為得到一筆意外之財而變得各懷鬼胎。雖然《迷》是改編自Irvine Welsh的小說，但暗地兩套戲又有些微相似之處，十分有趣。）
新版「Choose life」:
Choose life. Choose Facebook, Twitter, Instagram and hope that someone, somewhere cares. Choose looking up old flames, wishing you’d done it all differently. And choose watching history repeat itself. Choose your future. Choose reality TV, slut shaming, revenge porn. Choose a zero hour contract, a two hour journey to work. And choose the same for your kids, only worse, and smother the pain with an unknown dose of an unknown drug made in somebody’s kitchen. And then… take a deep breath. You’re an addict, so be addicted. Just be addicted to something else. Choose the ones you love. Choose your future.
舊版「Choose life」：
Choose life. Choose a job. Choose a career. Choose a family. Choose a fucking big television, Choose washing machines, cars, compact disc players, and electrical tin can openers. Choose good health, low cholesterol and dental insurance. Choose fixed-interest mortgage repayments. Choose a starter home. Choose your friends. Choose leisure wear and matching luggage. Choose a three piece suite on hire purchase in a range of fucking fabrics. Choose DIY and wondering who the fuck you are on a Sunday morning. Choose sitting on that couch watching mind-numbing spirit-crushing game shows, stuffing fucking junk food into your mouth. Choose rotting away at the end of it all, pishing your last in a miserable home, nothing more than an embarrassment to the selfish, fucked-up brats you have spawned to replace yourself. Choose your future. Choose life...But why would I want to do a thing like that? I chose not to choose life: I chose something else. And the reasons? There are no reasons. Who needs reasons when you've got heroin?
