I've seen it a thousand times, but then again you should not watch this with your family (your friends maybe) drama movies are just for you lonely saturday night I guess. It's a British movie, and it has been ranked 10th spot by the British Film Institute (BFI) in its list of Top 100 British films of all time.
It's a Danny Boyle's film, so it probably won't let you down. It has a very unique opening and some actors you might me familiar with. The film the film begins with Mark Renton's (Ewan McGregor) statement that unlike people who "choose life" (i.e. a traditional family lifestyle with children, financial stability and material possessions), he has chosen an alternative lifestyle of a heroin addict. Renton's close circle of football enthusiast friends are introduced: Sick Boy, Spud and Renton are all heroin addicts, while Tommy and Begbie openly criticise heroin use, even as they indulge in binge drinking and chain smoking. After quitting heroin, Renton struggles to adjust. The return to sobriety forces Renton to view his friends much more critically as they spend time together sober engaging in unconventional activities.
After a tragic relapse, Renton moves to London and starts a job as a property letting agent. He begins to enjoy the vibrancy of London, still clean off heroin, and saves up money on the side. His happiness is short-lived, however, as his 'friends' continually bring their dramas to him.
I hope you like it.
