When you think about football, it's the kind of thing where you'd have to wonder how anyone can make it in the sport without so much as kicking ball.

In other words, the utterly bizarre story of Carlos Henrique Raposo - known to his teammates as Kaiser - seems just that that it almost feels like it couldn't be real. And yet, it is. The outrageous story of Carlos Kaiser is easily one of the game's most outlandish and outrageous, and has now been turned into a documentary from the people who knew him and the man himself.

'Kaiser! The Greatest Footballer Never to Play Football' premiered at the Tribeca Film Festival some months ago and is currently screening at VUE Liffey Valley.
