Filmmaking terminology can be a bit inaccessible for the layperson feel free to boast in the comments section if you know what a key grip or best boy does on a movie set without looking it up but second unit isnt too hard to grasp; virtually every movie production of even moderate size utilises a second unit to film shots and sequences to complement the main action. The second unit is often responsible for action sequences that require stunt personnel rather than movie stars, and is considered a nigh-on indispensable element of modern moviemaking. Unless youre Chris Nolan. Taking his tendency to involve himself in every aspect of his films to its logical extension, Nolan has called second units an expensive luxury and believes that, rather than saving time and simplifying a film shoot, employing a second unit is an unnecessary expense that often produces precious little usable material. While acknowledging that many talented filmmakers use a second unit to great effect, Nolans view is: If I dont need to be directing the shots that go in the movie, why do I need to be there at all? The screen is the same size for every shot.
I watch movies and I watch sport. I also watch movies about sport, and if there were a sport about movies I'd watch that too. The internet was the closest thing I could find.
