The new Quentin Tarantino/ Robert Rodriguez collaboration, 'Grindhouse', has failed to knock comedy 'Blades of Glory' from the top spot in the US charts.

On it�s first weekend, the film made less than half of  Blades' weekend gross, coming in at around $11,500,000.

Whilst Tarantino�s films have never really set the US alight in theaters, it was expected that the added clout of Rodriguez (Desperado, Spy Kids, From Dusk �til Dawn) would push it further up the charts.

Tarantino has always bemoaned his native country�s reactions to his films, saying he always gets a better response from the UK (in one interview stating that his films don�t really �come home� until they�re shown in Leicester Square)

The Will Ferrell comedy continues to gain momentum in the popular family oriented Easter weekend - taking nearly $60million so far.
