Having been released in 1983, Scarface may be a dated movie by todays standards (this is very clear in the horrendous 80's pop music and bright hawaiian shirts used throughtout) but it still, to me, ranks among the greatest and most influential movies of all time.
Al Pacino stars as the unforgettable Tony Montana, a Cuban refugee who starts off dishwashing, but guns his way to the very top of Miami's cocaine empire. He plays the part really well: being ruthless and also coming up with some brilliant lines which orignially came from the film: "every dog has his day" being one of many that springs into mind.
The '18' certificate is deserved, though. If ever anyone wanted a lesson on how to take drugs, they would need to watch this movie as had drugs are used throughout, aswell as the bloody violence (the chainsaw scene being up there) and constant swearing.
Being very influential, this movie has been the main inspiration for Grand Theft Auto Vice City. Even Diaz from the game is a carbon copy of a chainsaw wielding bad guy from the film. Snoop Doggs album "every dogg has its day" is also influenced by the movie, with a quote from the movie appearing in the album.
This is one of those movies which just have to be seen. At 2 and three quarter hours, its not short, but the movie never drags and the final scene ranks among the government lobby shootout scene from The Matrix, the beach landing in Saving Private Ryan and the russian roulette scene in The Deer Hunter as one of the best and is perfect in summing up Tony Montana.
