For those interested in more details, I recommend the book https://www.amazon.co.uk/Boo-Hoo-Dot-Com-Story/dp/0099418371 . One of my favourite parts includes an investment banker plotting the IPO aboard a private jet only to learn that the company does not exist as a legal entity yet.
It's not a movie but I'd definitely recommend the book about the Boo.com fiasco: http://www.amazon.com/Boo-Hoo-Dot-Com-Story/dp/0099418371 .. I believe it was Europe's biggest dot com era implosion and you can almost see why from page one. An enjoyable read.
