Even though it once again contains my single biggest complaint about movies today (British actors being cast to play Americans, and to a much lesser extent vice versa), that looks terrific. Boyega, Williams and Britton are all awesome actors.
I remember when The Other Boleyn Girl came out and the biggest complaints from the English press were:
1. Eric Bana (Henry VIII): Australian
2. Natalie Portman (Anne Boleyn): Israeli/American
3. Scarlett Johansson (Mary Boleyn): American
As opposed to, you know, the rest of that garbage heap.
