Hi Phil,
It's a 2008 Czech movie and was released in the US in 2009. I saw it on TV here but it's available on DVD/Bluray from the UK:

I had another look at this 4 minute scene and I believe the grille is present throughout but the lighting angle in certain parts makes it look missing. As you say it's the expanded metal type, I've never understood why these appeared so commonly on Fords....?
