Another is a documentary about aliens by none other than Danny Dyer which is pretty funny too. Kind of surreal seeing him travel to America to hunt for alien evidence. Here's the whole documentary.
Below is a funny clip of him talking about in on 8 out of 10 cats.
Lets try and keep out those movies which were made bad on purpose so people will watch them ironically, I'm talking about Sharknado and others like it.
