I sit here at my laptop almost completely Ngog, sorry agog. Not from watching baseball's World Series between the New York Yankees and the Philadelphia Phillies, though that is developing into a compelling spectacle.

No, for once, it is an advert between the innings that has me gripped in a strange, almost catatonic state invoked by a disturbing mix of hilarity and abject horror.

The ad in question is a trailer for the forthcoming movie called 'Invictus', which is the Latin word for 'unconquered'.

Apparently, it comes out in a movie theatre near me on December 11 and if I hadn't seen the trailer I would have sworn it was cooked up as a spoof.

All you need to know is that Invictus will star Morgan Freeman as Nelson Mandela (well you can only play God so many times and Mandela is pretty darn close after all) while, get this, Matt Damon stars as Francois Pienaar.

Yes folks, it's a Hollywood blockbuster directed by Clint Eastwood about the 1995 Rugby World Cup.

Now, it took me a full 24 hours to even summon up the courage to type that out and commit what any logical human being would regard as a hallucinogenic mixture of words to print but it appears that the phrases “Hollywood”, “Clint” and “rugby” have now appeared in an English language sentence for the first time in history.

As far as I can recall, the last time rugby featured in an American movie in which a bunch of starving Chilean egg chasers trapped on a snowy Andean mountain-top decided to eat the entire front row in order to stay alive only to be rescued minutes later and therefore required to play uncontested scrums for the rest of the tour.

'Alive' it was called and a blockbuster it was not, featuring no star names unless you count Ethan Hawke. Invictus is at the other end of the scale and if Damon and Freeman are served up in the trailer we can be sure Mr Eastwood cast plenty of other familiar faces to portray the characters of that momentous tournament.

I'm just guessing, but do not be surprised if The Rock turns up playing Jonah Lomu with Abigail Breslin as hapless England wing Rory Underwood. Well that can't be anymore ridiculous than Damon as Pienaar. Can it?
