I apologise in advance for this grid.

Hard!!! But clever.

clever- too hard- rather let down by poor solutions. I got the gist but will now be forever wondering !!!!!!!!!!

James Bond - Goldfinger, The World is not Enough, Skyfall, Dr No
Tim Burton - Big Fish, The Corpse Bride, Batman, Beetlejuice
Alien - Alien, Aliens, Alien 3, Alien Resurrected,
Arnie Films - Total Recall, Terminator, Twins, The Expendables

Hope this helps! :)

Good idea - rescued by the explanations below otherwise I'd have had to hunt you down!! Nice.
